anyone found any good led bulbs to replace the H4 lamp?
You cannot replace a halogen H4 bulb with an LED for road use. You need to change the whole lamp unit to one designed for LED & E marked. Some seem to use items sold for Landrover. Uprated halogens as CBM linked are likely your best bet. I used Philips Extreme Vision +130.
I think you can change side lights for LED but not indicators as LED do not meet the wattage requirements not that M3W need changing being LED as original. My LED sidelight bulbs failed so went back to blue tint filament bulbs.
