Upping the wattage of the driving lights, Will the stock wiring/relays handle it?? Options

[aircooledtechguy]

I would like to add 100W H-3 bulbs to my stock driving lights on my '75. That's a 45W increase. Will the stock wiring handle it or am I in for a disappointment?? What upgrades should I do to pull this off?? Don't want to damage my ride. . . Thanks.

I used 85 watt h3 PIAA crystal ion yellow in my pilots without relay or any special wiring, no problems. Longest I ever had them on was an hour plus... AT 100 watts your on the edge and heat can be an issue too, I would not worry about the lenses if it is glass but behing the fogs there are wires for the fogs themselves and horns. 100watt relay is about $6 vs your system and peace of mind.. Anything over 100 watt and your asking for it without precautions.. I would go relay if I were you and wrap your leads.. When you really need to use them and not just playing with your car, you can't afford not see when you need to see...

I lived on Anacortes misty overcast dewy foggy rainy, do it right or even tone it down a bit, sometimes to much light especially white just makes it worse much worse, I lived in Colorado snow all day snow all night and if your lights are really white and high beaming you can't see sqwaut just a white wall, to much reflection..
