There are a few stipulations.
* Self levelling projector bulbs (usually garage don't check self leveling part)
* Headlight washers
* Colour is within range (I use 4500k - 6000k)
If any garage has an issue you can tell them to put the halogens back in til it passes and then swap em back, just don't put them into reflector housings because that is dangerous and you will glare and dazzle oncoming cars and most likely get pulled over.
I don't mind bending rules but I wouldn't be happy doing anything which endangers anyone.
Suppose I should say this is for info purposes only etc etc in case some pc warrior wants to point the blamey finger. :wink:
