my truck has dual lamps the highs and lows are seperate. I was wondering if anyone has made it so all 4 bulbs can be low or high. i know the 9007 has low and high and the 9004 has just low i think. could i take the low wire and splice it to both bulbs on the 9007 and do the same with the high beam wire? electrical is my weaker point.

 

yes its very doable look in the DIY section on the top of the page.

 

You'll want to look at beefing up you headlight wiring or setting it up with relays... you will be doubling the load if you do that.
