these are great because you can run a standard 55/60 watt bulb or jump up like i did and run a 90/110 watt bulb. first number being low beam; second high. quite a lot more than standard 30 or 35 watt. on coming traffic wont much care for you but boy can you see them .
like cjlandry said you will need to run a relay for each low beam and each high beam. this is really easy though once you get the relays and the relay holders.(most stereo stores have both for probably less than 15.00 for all). then use your existing low beam and high beam power wires now to turn on the relays. on a relay there are 4 wires.
1. chassis ground
2. power from battery
3. switched power(your existing high and low beam wires; green and tan i think)
4. power out from relay to headlights.
it is a lot easier than i described. kinda wiring 101. might sound like a pan but it is more than worth the trouble.
one last note the reason for the relays is to use direct power from battery to power up the lights, that way you have no high amperage on your existing wires and your old headlight wires just turn on the relays. all wiring can be done from the front of are. hope that helps. lemanster
