Thread: 2007 GP HID Harness and DRL Relay Chatter Question

Well, I guess nobody else knew so I just did it on my own and it works great. The whole project cost under $14 barring the HIDs themselves. Here's what I did. I bought a $8 HID relay harness from Ebay. I used a 4700uf 35V capacitor at the coil of the relay and a 3A 400PIV diode on the positive lead of the wire leading to the relay coil. I'm pretty sure I could have used a 2200uf capacitor but the 4700uf wasn't that much more money. It takes about a 1/2 second for the 4700uf to discharge to the point that the contacts drop out. So they stay on for a 1/2 second after being turned off (no more chattering). I put the diode in line on the + side of the coil wire to prevent any backflow of current from the capacitor to my DRL module that might cause damage. It works like a charm! Now my HID's come on as my DRL. They fire up every single time! If I'm not feeling too lazy I'll post pics or a video and a step by step if anyone is interested. Otherwise I'll just assume nobody cares by the responses (lack of) I received and I won't waste my time. "I'm only hearing crickets chirping right now"

Total cost: < $14
Relay harness from Ebay = $8 with free shipping "Took 4 days to get from CA to MO"
Capacitor = $3.50 ($6 or more if you get it from Radio Shack)
Diode = $1.79 (2 pack) at Radio Shack
Solder and Iron = $0 (had it already)
Heat shrink = $0 (had it already)
Electrical tape = $0 (had it already)
Liquid electrical tape = $0 (had it already) - Optional, but I use it to make all connections completely water tight. You can't waterproof with regular electrical tape and there are some things that you just can't heat shrink.
