I do not know that answer, but I havebthe same issue. It's like they are on a "low" setting. I'm wondering if a resister is needed in line to eliminate that issue?

Modern vehicles use electronic semiconductor switches (rather than electromechanical relays). These semiconductor switches have leakage current of a few milliamps when they are off. Tungsten type bulbs (incandescent, quartz halogen) draw relatively high current (hundreds or thousands of milliamps) to illuminate, and are not able to produce visible illumination at the few milliamps running through them when they are off. In contrast, LED bulbs draw much lower current for full illumination, and produce visible illumination at the few milliamps of leakage current of the semiconductor switches that control them. Placing a 1,000 ohm resistor in parallel with the LED bulb, as suggested in some of the other answers, eliminates the LED bulb illumination problem because some of the leakage current goes through the resistor and reduces the voltage across the bulb below the bulb conduction voltage, at which point the bulb stops conducting and all of the leakage current is diverted through the resistor.

An LED requires very little power to operate. Most cars now use electronic switching for low power outputs, unlike a relay or mechanical switch these may not totally turn off. Your regular bulb also gets the same amount of power but is less efficient so it burns it off as a slight amount of heat with no visible light.Hope this helps.

Hmmmmm, my lights are still ok, possibly a warranty issue... possibly a defective unit or bulbs...?

I actually did replace one of mine with an LED just to test it out and almost no light comes out of it. The LED lights just don't seem to put out enough light. :( I would love to find some LEDs that do though considering I am running like 15 of these all night long.

It should give off a little bit more more light. I also replaced with clear and LED(?) lights and I think it helped. I wished I found one that came with 6-8 light bulbs for more lighting, but I needed one that is simple yet conservative/elegant, less frills... I'm still very happy with this purchase.

I have no idea, maybe you turned them on and off and the light was trying to go away or maybe its just light reflecting of the tiny bulbs. Idk. But one thing is for sure bro. The lights are great. Ive had them for a really long time now and they are awesomem everyone ask me how come they are so bright and where did I get them. Once in a while ill turn them on and they wont work but I hit the switch on and off twice then they work without a problem.

Jay, if you find that an LED works, would you please let me know? I've been thinking of changing over when the present bulb burns out. Thanks

Sorry that I don't have a specific answer, incandescent bulbs have always seemed to have this issue. For my own, I went straight for an LED conversion kit, they're expensive but entirely worth it!

Mine does that the LED power meter, though it doesn't appear to light up at all. As the other person responded, is better to have the power meter icon in your system tray in lower right corner, easier to read, more informative, etc.

LEDS are supposedly brighter. Haven't used them. I'm familiar with CFL's. Hope this helps!

Mine does the same thing, it's common with LEDs. They have very little draw and should turn off completely when the car is off.

I would assume that it's a defective bulb(s) if individual LEDs are not light. This might also cause the flicker or it could be caused by a low power issue. LEDs pull much less power than traditional bulbs and can confuse some cars into thinking the bulb is actually burned out. My first assumption though would be a bad bulb.

You just need to check your bulb. Use a small flat head screw driver and carefully open your dome light. Take out the bulb and measure it. If its 1.25 inches long you're good. When you do put it in don't touch the light panels

Yes this is normal, it will have a white-blue tint similar to those LED bulbs you see on some cars. As long as its lit up through the little peep hole you're good.

Sorry. I don't know. I have a mix of LEDS in my RV and most seem to be as bright or brighter than the incandescent lamps they replaced.

It is normal John, mine does the same thing without any adverse effects. Actually, I noticed that after an extended period, they shut off completely. Keep in mind, its not the bulbs, but most likely our trucks that cause it. It just isn't a strong enough current to be noticeable with the standard bulbs.

If I recall correctly, instruction does indicate bulb is LED, but its been awhile since my install. The switch does not generate any heat and is actually cool to the touch, however, of the dozen, or so installed, several have failed, so no more red glow, but flickering. They have since been replaced and currently all are doing fine.

I noticed another brand allowed the bulb to be "re-clocked". I think I see that on mine, but in town I never get to go on high beam. I'll have to re-check the 3 tabs to see if I can rotate them up.
