I'll be taking my GTI abroad later this summer and I'll need some headlamp deflectors.
The last time I put some on my own car, I had glass lenses, so cleaning them off again was not a problem - a scrape with a blade and a wipe with suitable solvent. All clean again.
The GTI of course has plastic lenses and I don't feel inclined to use the same procedure for fear of causing damage.
I've also heard of damage being caused to the plastic lens by heat being reflected back from the beam deflector.
Anyone used them? Got any advice on fitting/cleaning off? Types to use?
I found this link http://www.europeandrivingkits.co.uk/contents/en-uk/d2_Headlight_Deflectors.html
Thanks

I go back and forward to Europe several times a year, and have never had an issue with just peeling them off after each use.
-
I'm 99% sure if you take the headlight off there's a metal tab you can flick which adjusts them to LHD legit. I think you can do it with them in-situ you just need small hands.
Deflectors are a pain in the bum, depends on the kind you use but I've seen them where without compounding the headlights (basically abraiding off the gunk) it's almost impossible to remove

Thanks - do you use any particular brand?

Thanks I'll have a look. That would make life a lot easier.

You could use Volkswagen's headlight covers/protectors. The part number for the Mk5 is ZGB1K0072100 and they come up from time to time on fleabay. If not try the dealership, I think I paid around £40 for the Polo 9n ones last year, shouldn't be too much different in price. They come supplied with vinyl beam deflectors to use when driving abroad.
Probably not to everyone's taste aesthetically, but they do function well for not leaving the adhesive on your headlights.

I would do that if you can't change the headlights from the inside.

I used a pair of Halfrauds deflectors when I went to France.
Not too hard to position. To aid removal, put the headlights on for a minute or two. It will warm the adhesive and soften it (a little).
Then just clean the residue with an IPA type cleaner.
I think the tabs are only on HID lights and not the standard Halogen.
The deflectors can only be used on Halogen lights. The HID light output can cause the deflectors to heat up and possibly melt the lenses. This is why washers are fitted to HID lights (The dirt heats up!).
My deflectors are in my sig pic and September of the forum calendar. :smiley:
-
Are you sure about that?
Pretty sure washers are fitted to the Xenon headlights because dirt on the lenses is more likely to cause dazzling or blind other road users...
Plus not forgetting that Xenons (@35w of power) run cooler than Halogen bulbs (@55w of power).. If you don't believe me touch a bulb after it's been on :happy2:
Further to that washers only ever come on when you, y'know, pull the stalk. Absolutely nothing to do with heat at all.
-
I have ordinary halogens and have always just used the stick on reflectors. Can usually get them real cheap on amazon. They can be a bit of a faff to get off, but it's not too bad :happy2:
-
Are you sure about that?

I was going to modify my post to state "also distorted beam patterns" but the forum stopped loading when I hit modify.
I understand that a Xenon bulb only runs at 35W but it is also worth noting that it is a much more narrowly focused beam, so all of the energy is concentrated on a particular spot on the lens opposed to the broad beam pattern of the 55W Halogen.
I am happy to retract my earlier statement if I am wrong. Thought I read it somewhere - possibly the instructions for the beam deflectors i fitted???
VW do say (RE: "Attaching adhesive strips to headlights"): "In vehicles with gas discharge bulbs, the head-light has to be realigned".

Pretty sure you are correct mate. I have read more than once that xenons were required to have washers because of the heat they generate.
-
Volkswagen also advise not to use the headlight covers on cars with Xenon headlamps. This must be another factor regarding the heat they produce.
-
Sorry but to stop false information spreading I must again point out that headlight washers are not there for the purposes of cooling the headlights.
1) They are there for removal of dirt from the headlight to stop/reduce dazzling from built up dirt on the headlights, as stipulated by EU regulations for the production of new vehicles.
2) They are only operated when you operate the windscreen washers, and even then I think it's only every 2-3 pulls rather than every single time. So unless you drive around while constantly pulling your headlight stalk backwards they are not being "cooled" anyway. You don't need a physics pHD (which I have!! ..not got) to work that out. :stupid:
From HIDPlanet (who are like the kings when it comes to all things Xenons)
The tungsten filament in a halogen bulb burns at around 2800°C during standard operating conditions.
The arc in an HID bulb burns between 2000-3000°C depending on the manufacturer and generation of bulb.
That is the actual BURNING temperature of the core part of the bulb that burns to produce light
Further to that:
3) I had Xenons in Hella Celis projector headlights for 18 months, I didn't have washers, and never once did I burn or melt my headlights in any way..
I'm sure the places you read that Factory Xenons came with washers was to cool the headlight, are the same places than says diesels with a decat will fail the MOT on emissions! :grin: :grin:
The reason that VW likely do not advise using headlight covers for Xenon lights is because of the fact that the beam pattern would not be correct.
Also that they have the tab on the inside of the headlights to change them...

Sorry Jay. Only going on what I've read elsewhere. Must be duff info, glad you cleared it up.
:happy2:

Thanks - do you use any particular brand?
I just use the cheapo ones I found in Halfrauds and, as others have stated, use an IPA type cleaner to remove the gunk afterwards. Never had any issue!

Used the RAC ones bought on Ebay for £3, easy fitting and easy to remove when done, worked a treat (Altho only drove for 2 hours in dark)

I'm sure you know what you're talking about, but I wasn't suggesting that the washers were to cool down the lights. Just meant that they might clean off any dirt baked on by heat to stop dazzling. I probably read about it in car magazines. Again, not doubting you, was just saying what I read.

xjay1337 - RE: my earlier posts
I in no way stipulated that the washers are to directly cool the lights.
My understanding was that the focused light output heats up the dirt - which in turn heats up the lens. It's called conduction (I'm sure you understand conduction with your Physics PHD! :notworthy:) If there is no dirt, the light energy passes straight through the clear lens unimpeded! Simples :happy2:
So in conclusion:
Dirt on the lens = heat on the lens
No dirt on the lens = no heat on the lens
The lenses will be cleaned as you clean your windscreen so as to not allow excessive build-up. 1st, 5th etc.. trigger of the screen washer.
Please read my posts properly before replying with sarcastic comments.

It's not sarcastic at all. It's the fact that you believe that the reason Xenons have washers is because of heat.
Which it is absolutely nothing to do with. I understood your post perfectly and now you need to understand you are wrong, and I was trying to explain why - which you have completely ignored.
As I've explained (in a non-sarcastic way I made one jokey comment and it's got your back up?) it's because of the fact that dirt on the lens can possibly dazzle other road users by defracting the beam of light in an less than uniform pattern as the light passes through the lens.
A VW dealer told someone (wrongly, after all they are bigger idiots than most owners) who made one post on a forum that you can't fit the stick-on deflectors to the headlights because of heat and you take it as gospel..
As I said I had Xenons with no washers for a very long time and had no problems what so ever.
Most dirt comes from rain.. but when it's raining you're using your wipers (not washers) unless you believe that the falling rain and subsequent spray from the cars infront and then dries later as dirt, magically cools your headlights.... Lol.
I will re-itterate, the reason that Xenon light systems have washers is because of the glare which MAY be caused by light being refracted randomly and dazzling and blinding other users due to the more intense beam pattern. Not more intense temperature, as it is COOLER than a Halogen bulb.
But hey, if you want to believe that then that's up to you and that's fine. Every single legislative body in the world must be wrong, our mistake.

I used these on my last car ...only on a week and they left sticky crap on the headlights ...so now I bought these

Got them on ebay ..genuine vw golf mk5 covers and vw supply beam deflector stickers with them ...they even have guide marks to make it fool proof to fit ...having both a jetta and a golf its ideal for me ...plus my lights are like new and I don't want to have to remove sticky crap off them ....if your lights have a lever in them to flick between left and right then all this does is flatten the beam to help stop blinding on European roads ...but it doesn't convert them to fully left hand drive

Got the headlamp covers as Mrs MrDo has family in Fance. Covers work fine on my Halogens. Simples.
Use to have stick on ones but they are a faff. Best to use wind screen washer fluid to remove sticky residues. Consider covers if you'll be popping over more often.
