1998 Ram 1500.
Will the factory headlight wiring be able to take the draw of a 90 / 130 watt headlight bulb ?

 

I wouldn't recommend it. They're kinda marginal with the stock lamps.

The hot ticket is to use some switching relays so that the factory circuit only powers the relay coils.

 

This is for snow plow lights.
The ones on the snow plow just aren't bright enough for what I want.
The snow plow wire harness ( I installed ) with light adapters.
When you turn the plow lights on, the trucks lights go out.
I bought some 90 / 130 watt bulbs for the plow lights, but they still get the power from the factory harness and I thought the wire looked a little small for those bulbs.
I was hoping they would be big enough so I could continue to use the factory light switch as well as the factory high / low beam switch.

I ended up running new legs to the plow lights and put in two toggle switches.
I ran a fused 14 gauge wire to each light ( one feed for each light ).
One toggle switch for on/off and the other for high/low beam.
Now I don't have to worry about melting down the factory harness.
I hid the on/off switch so you can not see it and the high/low I put up by the ignition key as high as I could.
It doesn't look to bad.
