I have a 2015 tahoe and I replaced the factory bulb with an led conversion kit. When vehicle is off they work, and as soon as I start the vehicle the shut off after 3 to 5 secs. Help!

1. My HID Kit or LED Kit does not turn on at all. If you install your HID kit or LED kit and they do not turn on you may have a reverse polarity issue. What this means is the power and ground wires of your vehicle's stock harness are reversed.
To reverse polarity on HID headlights, you must rotate the 2-pin oval connector on the HID ballast by 180 degrees in order to reverse the orientation of the plug.
To reverse polarity on LED headlights, you simply rotate the connector which plugs to your vehicle's factory harness by 180 degrees.
This problem is unrelated to the HID kit or LED Kit. It is an issue with the vehicle's factory wiring orientation. Halogen bulbs are not affected by polarity therefore some car manufacturer may have their polarity reversed.
If your HID kit or LED kit still doesn't light up after reversing the polarity, your headlight fuse might be too weak. Upping the fuse by 5 amps might do the trick.
2. My HID Bi-Xenon high beams or low beams are not working or are inverted. This is a similar issue as above, the polarity of the connector's pins are not correctly aligned. Bi-Xenon HID kits have 3 pins on the harness connector for ground, low beam and high beam connections. You will need to release the pins inside the connector and reorder them. You may need several tries to find the proper orientation. Look inside the connector and with a precision screwdriver you can release the pins and reverse the wires.
3. My HID lights are flickering. Flickering usually means the car is unable to supply enough power to the ballast. You can easily test this by connecting the HID kit directly to the car battery. If the kit works, it is a power issue. To resolve this, you will need a wiring harness.
If your car has Daytime Running Lights (DRL) flickering is usually caused by the lower voltage needed to run the DRL at half power. The car's factory harness does not provide enough power to the ballasts. If the flickering is caused by the DRL you will need a wiring harness or have the DRL disabled (this may not be legal in all areas).
Flickering can also be caused by the vehicle's onboard computer failing self-check test due to the new HID kit you just installed. This can easily be corrected with a set of warning cancellers (capacitors).
4. My LED headlights are flickering. LED lights may flicker on some vehicles, this is caused by the vehicle's onboard computer failing self-check test due to the new LED kit you just installed. This can easily be corrected by adding a set of warning cancellers (capacitors) to your setup.
5. My HID kit works sporadically. If only one side turns on from time to time or your lights work inconsistently, you probably have a power issue. You will need a wiring harness to power your HID kit directly from the car's battery.
If you install the wiring harness and still experience intermittent firing, please check your wiring connections. Make sure the power terminal is properly connected to your car battery and that the wiring harness is securely grounded.
6. Only one side is working on my HID kit or LED kit. If one side sometimes doesn't turn on it could be caused by a bad bulb, HID ballast, LED driver or wiring. To help identify which component is defective follow these steps.

1. Swap the ignitors to opposing sides (not applicable for LED kits). If the problem is reversed, you might have a bad ignitor.
   • This step will check if you have a bad ignitor. The ignitor is the black rectangular box that is plugged between the ballast and the bulbs. To perform this test, please swap your ignitors to opposing sides and note what happens to your kit.
2. Swap the HID ballasts or LED drivers to opposing sides. If the problem is reversed, you might have a bad ballast.
   • This step will check if you have a bad HID ballast or LED driver. The HID ballasts or LED drivers are the two metal boxes that came with your kit. To perform this test, please swap your HID ballast or LED driver to opposing sides and note what happens to your kit.
3. Swap the HID or LED bulbs to opposing sides. If the problem is reversed, you might have a bad bulb.
   • This step will check if you have a bad bulb. To perform this test, please swap your bulbs to opposing sides and note what happens to your kit.
4. If none of the above helps, please check for loose connections. If you installed a power relay harness with your HID kit, make sure you have properly grounded the harness.

you need the check your kit bulbs / ballast [ or retrofit kit depending on manufacturer ] that they are compatible with your vehicle most are designed to retrofit with halogen type systems

yes they can be replaced but you would have to handy and confident with a soldering iron if there isn't a small socket that the bulb fit into. Most if not all the backlighting bulbs are those clear bulbs with the blue covers over them. remove the LEDS from the twist socket without breaking the leads and they would have to be soldered directly to the circuit board like the existing bulbs.

15. Remove the facotry headlight from the BMW. First remove the front panel cover below the headlight to access the bottom screw of the headlight housing. There is also two screws on the top of the housing.
16. Once you have remove the headlight, turn the headlight around and remove the bracket that holds the Ballast. Then remove the ballast using a philip screwdriver.
17. Unplug the wire from the ballast, and then remove the Xenon Plug from the housing. Put the Ballast aside.
18. Carefully remove the D2S Xenon Bulb from the factory housing. Once you have remove the bulb, transfer the bulb to the Spyder headlights.
19. Remove the bracket from the Spyder Headlight, and then install the ballast on the housing like the original. Once you have put the ballast on, put the bracket back on.
20. Remove the Panel Cover bracket from the original headlight to the new Spyder Headlights as shown here.
21. STEP:
22. Install the Spyder turn signal socket if the orignal does not fit, unplug the factory plug from the harness and plug the new one on.
23. Install the Spyder Headlight back on to the vehicle. Plug the Harness back on, the halo/L.E.D. Wires is connect to the Parking lights. These wires are optional to your vehicle, you do not have to wire them together.

BMW e46 HID Headlight Replace

I have heard some complaints on this but if you are the owner of any vehicle with air ride you know it can be costly to fix. You can fix your whole air ride system and save some money if you go to Strutmasters.com and get one of their non air conversion kits. No more leaky lines or bags this takes care of it all!

you may have put cables on backward or bulb

good luck finding bulbs, not sure but they might be LED's, most aftermarket shops have suppliers that they send the unit out and they will repair.

Hi,

I had a similar problem when I fitted LED sidelights, they worked with the key turned but as soon as I started the engine they went out again. The "bulb out" error came up on the dash too. It's caused by the low current consumption the LEDs have, and thus the computer thinks a bulb has blown. You can get resistor kits to solve this but it's a lot of hassle. I just went for blue coated sidelights from a company called Ultra bulbs, they produce a bright white light.

99 - 04 grand am.

I had the "service vehicle soon" light come twice with in 1 year. First the heald light bulbs were gone. Replaced the head light bulbs and after 2 starts the "service vehicle soon" light was gone.

The second time the DRL - #194 amber bulbs were gone. Replaced these and the "service vehicle soon" light was gone after 2 starts. The DRLs are housed in the headlamp housing, the tiny bulbs beside the head light.
