My '01 Tahoe goes through the daytime running light too much. Is there a reason for this? I may need to break out the VOM and check for bad grounds or excess voltage.

You see it all the time - a GM product going down the road with a light out

I manage a fleet of around 100 GM trucks...they all lose a bulb every 6 months or so. Think about it, the lights run almost anytime the vehicle is in motion. That is a lot of running hours.

I'd check and see if they have a LED replacment for those things. If there isn't one available there should be.

Dont know if it works on your year but if you lightly, i mean lightly press down on the E BRAKE your lights will go out. The down fall is your e brake light in the dash stays on.......

3157 is the bulb number. There is an LED replacement.

Actually the part number is a 4157, but the 3157 is a more common replacement. The LED conversion bulbs for the 3157 design are not typically a very well built product.

My 00 GMC has the orig lights in it. (now they will probabally burn out)

My 90k mile '00 Olds also has originals. I haven't really noticed the problem around here.

I agree, i see tons of them that way. I have owned 2 of the nbs trucks and bout every 3 months they go out. The connectors on all of them i have seen are black, like they get too hot. Not sure if that has anything to do with it or not.

They are not continuous duty bulbs, and yet are in a continuous duty application. I used sylvania long life bulbs, and never had to replace another.

I've seen so many of those out in trucks I started to wonder if they were only supposed to have one on. Good grief.

The biggest problem is that they will not illuminate unless the vehicle is in drive without the parking brake on...it makes it pretty difficult for the average driver to even know they are out or not. The only way to check is to have someone else hold the vehicle with the regular brakes (or do it my which I highly discourage and stand in front of the vehicle in gear with no one holding the brake, using a block in front of the wheels).

......or you can do as I did on my 02 Tahoe as soon as I drove it home from the dealer - pull the fuse and drive without them. They never burn out that way and you don't look stupid running around with only one lit :thumbsup:

I'm lucky if I get six months out of each bulb in my o1 Tahoe. I leave spares in the glove box.

Dennis, the easy way to see the bulbs that are out is to look for the reflection on the vehicle in front of you at a stop light. Pickup tailgates are good for this.

If only...

I have a Trailblazer that uses the low beam headlights as the damned DRLs. You can't pull the fuses or the low beams don't work.

GM arrogance at work. But at least they're going bankrupt. Do you suppose that ****ing off your customers might lead to financial disaster? Maybe they should do a twenty-year study to find out.

OK, just put the VOM on there to see if anything is going on...

14.1v between the leads, 14.3 from the hot wire to battery ground. I did a resistance check for the ground wire to the batt neg, about 1.0-1.3 ohms. Only I didn't do was rev up the motor...couldn't b/c teh trans has to be in gear for the lights to come on!

Sound OK?

I have replaced one light socket and one bulb in my 02 1500HD, lots of em at work though, the bulbs that is. the canyon/colorado take a 3757 bulb, the tangs are different.

I've often wondered why all the GM trucks and SUV's I see have been running around Popeye'd for the last few years.
