Ok i have my DRL's and AHL's disabled. As some of you may know that the quad beam mod doest work in combination with the other two mods. The DRLs will still come on. My question is will it work with HIDs. I have HID highs and lows and I remember reading that someones drl's didnt work becuase the ballast were not getting enough power. If I did the quad beam mod now im assuming it will work but will that hurt the high beam HID's? They wont go on as DRL's because they are not getting enough voltage.

 

Well, i have had my high and low beams for about a year now and i just recently disabled the DRLs, the highs still look great and i haven't noticed any damage but i'm no electrical master

 

/did the DRL's still work with the HID's?

 

no they did not, they never turned on, i ran it like that for about 8 months before i disabled them. but like i said, i'm no expert.

 

the drl's are just low beams with reduced voltage to make them a little dimmer than full low beams, the lower voltage might not have been enough voltage to power the balasts to power the hid's

 

yes, i know that but i was wondering if that would be bad for the ballast. since they are getting a lower voltage then needed.

 

Actually the DRL's are high beams and the power running to them is actually more of a "pulse", like a sinusoidal wave.. GOOGLE if you want lol...

The "no HID DRL" issue has been solved with a capacitor, but I didn't feel like doing this on my Blazer, so I sold the HighBeam HID's instead. The capacitor goes on 2 pins on the high beam relay, between the power and the DRL pin I believe... I remember reading it on a Mitsubishi forum and wondering if it's work for our trucks.

 

Yeah, I knew they were high beams but didnt bother saying anything. Ok, it sounds like I will be fine. I dont want DRL's. I was just worried about damaging the ballast because its not getting full power or its "pulsating".

 

There is no pulse width modulation going on with the DRLs on these trucks. What happens is the relays re-route the power and ground to the high beams making it so that the two headlight bulbs run in series with each other. When in DRL mode, chassis ground goes to one bulb, the positive from that bulb runs to the negative of the other, and the positive on the 2nd bulb receives +12V power.

 

my HID's turned on with the DRL's but that isn't good for them because they aren't getting full power. I didn't feel like disabling my DRL's so I put a peice of tape over my light sensor so my low beams are on all the times at full power. I like it better this way then I never have to worry about turning on my lights.
