number plate bulb problems

[rolfgti]

Ok the cars doing my nut in at the moment, I must have gone through about 4 sets of led bulbs cos they keep blowing but only the left side every time, just wondered If any one knows  why the left is going  and not the right also if any one knows of some good quality led bulbs?
 Thanks

I paid 7.99 for mine and 8.99 for the front side lights on eBay got proper circuit boards built in them and still working a year on. The fronts needed a little sanding down as there flat but look fine in the lights.
