I wondered if I could replace the factory H4/9003 55/60w bulb with higher watts 80/100w aftermarket bulb.
My choice is Hella Optilux XB H4 80/100w. Would the higher watts damage the wiring or other equipments?
Any other better choice?
a higher output may or may not damage the OE wiring for the head lights. Since this is the primary headlight, there is a large possibility that it may burn the wiring, you may have to have it upgrade it to a bigger gauge wire. Or you can just bring up wattage to 65w low and 85w high? I too have use Hella Extream and Optilux on another car, but i don't really know the gauge of wire used on the RL.
