Default Headlight relay kit?

if you have installed a relay kit for their headlights I have some questions

-What components did you use?

-How did you route the wiring?

-Where did you locate the relays?

I am having issues with one of my Headlight connectors and I feel that if I am going to fix the connector, maybe I should fix the circuit

Thoughts?

I got the relay kit from Daniel Stern Lighting. At the same time I got a set of Ciebe lamps. The relays are mounted on the left front fender well. I ran a 6ga wire from the battery installed a 30amp fuse and ran new 12ga wire for the headlights. I need to find a new pair of headlight sockets after 7 or 8 years. Look for ceramic ones if you can find them.
If you check the voltage drop you'll find it's about .5v. Lights fall off quite a bit with voltage drop.
The big deal is the Ciebe lamps and overwatt bulbs (not the do nothing blue silverlight junk). E-code lamps and overwatt bulbs make a tremendous difference driving at night and in the rain. The lamps shine down on the road not all over the place. I'm running 90/110w bulbs. I've never had oncomming drivers flash at me like I was blinding them.
Factory wiring would just blow the fuses instantly and melt out the headlight and dimmer switch.
Overwatt bulbs won't last forever. The first set of 100/130w bulbs lasted about 2 years. I was doing a lot of long distance driving at night. I've had better luck with the 90w low beam bulbs.
I have nothing to compare my lights to except the dim stock lights. If you upgrade you won't be disappointed. I spent about $200. HID is another option. I like the white light and I still have both high and low beam.

Thanks

How/where is the 12ga routed to the passenger side?

I think I am going to fix the current issue then work on the upgrade

I am just looking to improve the power going to the E-Code H4s I have.. only running 55W at the moment, but I noticed last night they are quite weak, so I figure start with the power first, bulbs later

I've always maintained that if you provide MAX VOLTS to the even stock lamps a person should see dramatic improvement. Providing MAX VOLTS requires good lamp connectors, appropriate gauged wire and RELAYS to trigger/power the lamps.

Stern is the "go to guy" for lighting but there's sufficient reads that with simple wiring understanding and principles you can DIY and be done with it.

Nearly every late model production car is done with relays for highs and lows.

stock wire sucks on the headlights. Look at the fix from the circuit doctor to get them to work right have not done it yet have to turn the fogs off to get low beams

Are you referring to adding the additional Bulb?

Ah, if I add the relay kit to improve the voltage to the headlights then the additional bulb is not required
