Do a search on this board for headlight problems. I would be really leary of going to that high a wattage, as the wiring was designed for the 55/60. That's why I run a Silverstar, same wattage as factory with no fear of melting my wiring.kram2691 said:Here's another idea, I wonder if anyone has experince with this. I have a mazda miata. Just so happens the pop up headlights on this car use H4 bulbs. I purchased non DOT approved offroad motorcycle bulbs and reflectors and put them in the car. They are 80/100w. Seems like with all the HID and Xeon(?) bulbs in the pricey Euro cars now that annoyingly bright headlights are more and more common. Same issue as the motorcycle, lighting is a safety issue in this small car. Lighting is 100% improved with these extra bright lights. I did quite a bit of reading up on this common miata mod before making the change. There was some concern about higher current draw on the wiring harness, and i probably wouldn't drive for extended periods with the high beams on, but so far the stock wiring has been fine, and it's been 3 years since the mod.
I wonder about putting the same bulb in my Shadow Spirit 1100. Anyone have experince with this?
