Another Hid Question...clueless And Need Help

[okc666]

i have an 07 classic body style silverado. im wanting to install HID in the low beams and foglamps. so at the risk of sounding completely stupid....

if i install the HID kit in the low beam, does that mean the lights will be on all the time while driving because my low beams are also my daytime driving lights?

if and how can i correct this? do i manually turn off the running lights during the day every time i get in the truck?"

i noticed theres a light that only comes on with my keyless entry, is that its only function or does it do something else?

thank you in advance.

I believe your DRL is indeed the same bulb as the low beams. However, I also have heard that they are run as DRLs with a lower voltage to ensure a long life. My understanding is that you have two ways to go: 1) disable DRLs by pulling a fuse. or 2) power a relay with the Low Beam circuit that relays direct 12-14v power to the HIDs (apparently, the DRL reduced voltage is enough to throw the relay) BTW, I would never get power directly from the battery, I'd go to the fuse box and tie into an unused bus and fuse it.

If you have a "Classic" body style (GMT800) your DRL's are NOT your low-beams,Your DRL's are separate bulbs located below your headlights (next to the turn-signal bulbs)

while driving today i noticed the lamps that where lit are the same lamps that are lit now (dark outside). the lamp on the bottom, next to the turn signal only works when i unlock the doors with the key fob, and it goes out when the truck is started.

In the daylight,when the trucks in gear,those are your DRL's. (They do also serve the purpose of "illuminated entry" when you use your key fob to unlock the truck)

From the service information....

 

Daytime Running Lamps (DRL)

The daytime running lamps (DRL) will operate when the ignition switch is in the RUN position, for automatic transmissions (A/T), the gear selector is not in the PARK position, the headlamp switch is in the AUTO position, and for manual transmissions (M/T), the park brake is released. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate. The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level. When the BCM receives this signal it will either turn on the DRL or the headlamps for auto headlamp operation. Any function or condition that turns on the headlights will cancel the daytime running lamps operation. The DRL can be manually turned OFF by depressing the AHL/DRL switch in the headlamp switch. The AHL/DRL defeat switch sends a ground signal through the DRL switch signal circuit to the BCM. The BCM then turns OFF the DRL and headlamps switch to manual control. When the AHL/DRL are manually turned OFF at the headlamp switch, the AHL/DRL will default to ON with the next ignition cycle. **The DRL are separate lamps independent of the headlamps.** With the headlight switch in the AUTO position, the DRL will either be turned ON or OFF, after an approximate 8-second delay depending on whether daylight or low light conditions are sensed. The DRL 10-amp fuse in the underhood fuse block supplies battery positive voltage to the DRL relay switch contacts and relay coil. When the BCM energizes the DRL relay , the DRL receive voltage on the DRL supply voltage circuit. Ground for the DRL is at G100.

 

From the owners manual....

 

Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional DRL are required on all vehicles first sold in Canada.

 

The DRL system will come on when the following conditions are met:

 

• The engine is running.

 

• The ignition is on.

 

• The exterior lamps control is in AUTO.

 

• The light sensor determines it is daytime.

 

When the DRL are on, only the DRL lamps are on. The taillamps, sidemarker, and other lamps are not on. The instrument panel is not lit up either.

 

When it begins to get dark, the automatic headlamp system switches from DRL to the headlamps.

 

When the headlamp switch is turned off, the headlamps go off.

geeeeez... thank you ms3dale. i appreciate all that typing. i wonder if theres a sensitivty setting on the DRL sending unit.

anyhow, what if your waiting for a signal and your under an overpass, the DLR will shut-off and low beams will light up, until you leave the overpass right? do you think the on and off is bad for the HIDs? or am i overanalyzing?

[MS3DALE]

Yes,Again,From the service info...

 

"With the headlight switch in the AUTO position, the DRL will either be turned ON or OFF, after an approximate 8-second delay depending on whether daylight or low light conditions are sensed"

 

They put an 8-second delay feature in there so the headlights/DRL's aren't going "on-off/on-off" unless needed to.

[okc666]

thanks for that info. i appreciate your replies.

as stated if you put a kit in it will operate exactly the way it does now as the kits turn on the ballast with the low beam power wire.

 

are you going to use a hid projector or hid reflector? or scatter the light with your stock halogen reflectors which dont focus the light and dont have cutoff shields and blind every driver you pass as if you had high beams on? [and illeagal in most states]

Illegal. And its illegal on a Federal Level because there is an added ballast.

[okc666]

i live in the ghetto of pomona california... everyone here is illegal.

Wish they were illegal here aswell, i hate HIDs wich are not fitted in projector light housing...

 

I'm still going to put HIDs in my Low, High & Foglights

Everyone on there its illegal rants need to relax. How many people lift or lower there truck without reaiming the headlights? I pass some people with lifts and there lights blind the hell out of me even without hid's. Yes its annoying and dangerous but instead of telling this guy its illegal why don't people tell him to make sure he re aims his headlights or use a projector or reflector and quit telling him its illegal...most people are going to do it anyway so you might as well give him some advice on what to do so he doesn't blind other drivers.

There's nothing wrong with telling him it's illegal. Better he know before he installs them, than a cop educates him later.

 

I think we should all get the most powerful lights available and aim them as high as we want. Then we can see who "...can handle it...". Kind of a "chicken" with lights. Maybe we can reduce oil consumption by crashing a few people?

 

To you guys thinking of HIDs, I recommend you buy some for the fog position first and see if you really think its a good idea to put them in your lo beams. My HID fogs are so bright and have so much scatter, that I can drive down a street and light up the balconies on the second story of houses along the side. So, even though I've bought a set of HIDs for the Low Beams on the 99 GMC, I won't install them. With auxilliary lights like fogs and driving lights, you at least have the ability to turn them off when there's oncoming traffic.
