One light had the bulb out of place because the head was not properly installed. The second (ordered 2 lights) the tail switch did not work. Sent them an email regarding the issues over a week ago, and no response.

One of the LED assemblies had a bad diode, with only three of the four lights working. Other than that it was easy to install and a nice (Not annoying) modern look.

It was the right size for the lamp but unfortunately one of the two bulbs shorted out within the hour. The other one worked as intended. The quality is therefore not what I expected.

One of the light fixtures doesn't work. Can I get a replacement or will I have to return the entire thing?

Received with one lamp broken, replaced with higher wattage photo CFL's.  Now quite functional.

Altogether possible that my warmers were shorted, but one bulb lasted only about a week!!

The lights are great, but some of the bulbs were broken. When I ordered the lights themselves, some of those bulbs were also broken.

One light was defective out of the box. Had to keep and reuse one of my old lights that still worked.

One of the bulbs came dead and another buzzed in a standard socket to the point where we replaced it for the old non-LED light.

I could only use 6 out the 10 bulbs due to variations in the light output and the color.  It seems to be a quality control issue.  All of the worked but there was such a difference in the color that it looked weird in my vehicle.

I'm still satisfied given the cost of all 10, though with the above caveat

The plug for the light bulb was of wasent able to pug it in right and the other thing the alignment for the screws were off as well.

Super bright but one of the bulbs is loose in the bulb socket, not the headlight socket where the bulb attaches to the headlight, but the bulb itself wiggles around in its own base. Driving down the road, the light wiggles making the projected light wiggle up and down. Looks terrible.
