LED's now no cruise control

[DanDman]

I installed LED bulbs in the taillights of my '04 LT. Now my cruise control doesn't function at all. Reinstalled the incandescent bulbs, everything works again.
Is there a certain kind/brand of led I should install? The ones I installed are Phillips.

you need to add a load canceler you don't have canbus only the hybrid GMT800s* & 900 have CANBUS

I should have specified that it was the brake lamps. Do the brake lamps need a resistor?
I will be installing a led compliant flasher for the turn signals

yeah probably.. a normal light bulb is a resistor that is what the controller is looking for

Yes the rear brake lights also need resistors

 

[DanDman]

Would these work? I'll have look at my wire harness tomorrow and see if they will

Did you ever get this figured out? I was planning to add the Philips LEDs to my 2003.

Yep 50w 6ohm Resistors and cruise will work again

 

[Flingflanger]

can verify you just need the resistor on your brake line.

No point of swapping to LED if I need to waste 50w of electricity each time I brake.
I'll go back to incandescent brake bulbs.

"No point of swapping to LED if I need to waste 50w of electricity each time I brake."

This is some strange logic. You're not 'wasting' electricity. The same amount of electricity is being used every time you push the brakes. Doesn't matter if you have a resistor in place or not. Think of it more like you need to slow the electricity down now that its not being in hampered by those needy incandescent bulbs. Its too quick back to the relay so the relay can't figure out whats going on. Slow it down the CC relay will know whats going on again and you'll be happy. Its less than $10 and super easy to do.

But it’s free electricity

That's not what wattage is.

I like your logic! This LED craze is bizarre, 2000 watt Led headlights and they wonder why electrial problems started. My personal favorite is Blue Lights on everything- Right, ruin night vision for ten minutes with every blue glimpse. Ever wonder why airplanes have red lights?

 

[91RS]

Except LED headlights aren’t that bright (light bars are but look how many individual diodes it takes to be that bright, that isn’t fitting inside a stock headlight) and have only been around a couple of years. HID headlights are what people have been using for years that are “blue” (8000k+). The problem with these isn’t anything to do with the color, it’s using HID bulbs in a reflector designed for a halogen bulb and then they usually don’t adjust the headlight aim either. Factory HID’s look blue because of the projector lens but the light is actually 4300k which is slightly yellow and has the most light output. That’s why people get the “blue” lights so it looks like the color projectors give when you’re looking at them.

 

[exp500]

Sorry, meant blue interior lights, exterior showoff lights. I understand bulb tints and temps. And you are correct- the reflector/lens is the most critical part.

This resistor will waste 50w in pure heat . That's a waste for me.

Nope. You're producing it with your gasoline.

Lol.
