rverdoold Posted July 19, 2007 Share Posted July 19, 2007 Normal H4 lamps are 55 watts, i found some rated 90 to 100 watts. Is it possible to use these or will i burn things (fuse, wires?) Link to comment Share on other sites More sharing options...
nipper Posted July 19, 2007 Share Posted July 19, 2007 Well your doubling the wattage, so yes you may cook things. You need to wire in relays and heavier wiring to take the extra load. nipper Link to comment Share on other sites More sharing options...
jamal Posted July 19, 2007 Share Posted July 19, 2007 yeah there is a really good chance you will melt the housings even if you upgrade the wiring. Plus it's illegal. Get some narva rangepower +50s (or equivalent), clear the lenses, and upgrade the harness though. If you still want more light get some aux driving lights.

I would agree that you'd need some relays and heavier gauge wiring to make sure you don't melt the connectors. Link to comment Share on other sites More sharing options...
jamal Posted July 19, 2007 Share Posted July 19, 2007 Most likely illegal, but on the plus side I think he has glass e-code headlights. So the good bulbs and a better harness would be a good idea. Link to comment Share on other sites More sharing options...
rverdoold Posted July 20, 2007 Author Share Posted July 20, 2007 Yes i have Glass E4 light units and metal reflectors. But i dont want to modify too much. I already have 2x 100w (hella) fog lights completely relayed and heavy wired. I have seen people cleaning their headlights with toothpaste because they become yellowish. I have never seen that over here. Is it because the european light units are different or different weather? Link to comment Share on other sites More sharing options...
Reveeen Posted July 20, 2007 Share Posted July 20, 2007 I have never seen that over here. Is it because the european light units are different or different weather? Your lights have glass lenses, ours are plastic, the plastic yellows over time. Bosch makes an off-road bulb that is 80W/100W (low/high) that I have run in motorcycles. I would not try them in plastic lights, and we have to remember Japanese made headlights are not as focused (or "directed") as european made headlights, turning up the wattage may very well blind on-coming drivers.

Legacy777 Posted July 23, 2007 Share Posted July 23, 2007 You'll probably be fine. An upgraded wiring harness & connectors with relays isn't a bad idea, but you'd probably be ok. Link to comment Share on other sites More sharing options...
