There's a few complaint found with these lights, and LED's in general. Once you understand how to easily correct these issues, these are great lights. IF LIGHTS DON'T WORK It's not just the Auxbeam, but most LED lights are not wired the same way as the halogen's that are currently in our cars and trucks. I may just be referring to U.S. vehicles here but I don't know. For the LED's with two pronged connectors (like the 9005's and 9006's), merely flip the connector. The locking connector on the harness will be on the wrong side of the locking pin on the light. If you don't want to re-wire your harness, just zip-tie the connector together to assure they don't come apart. IF THE LIGHT BEAM IS NOT CORRECT I've seen complaints of scattered beams and of beams too narrow. This problem comes because of the design of the light AND the design of the light housing. Because of the large tabs on the halogen bulbs, the LED bulbs can be installed in two ways: with the LED's to the top and bottom or with the LED's to the left and right. Technically, the bulb is designed to be installed with the LED's to the top and bottom; but headlight housings may cause you to reinstall the light with the LED's to the right and left. How do you know which to use? I'm glad you asked. Look inside you headlight housing and notice how the reflective dome is made. If your using this 9005 bulb, you should have two reflective domes; one for low beam and one for high beam. Is the single dome round or rectangle? Some domes are completely, or close to, round. Some are rectangle with very little reflective mirror to the top and bottom. If your dome is round, you are more than likely going to install the light assembly so that the LED's are at the top and bottom. If your reflective dome is rectangle, you will install your light assembly so that the LED's are to the left and right. To install the LED's to the left and right may take a little finagling as they are technically designed to be installed to the top and bottom. It is not hard to accomplish, you just have to find the right position to start in that you can make all three tabs fit simultaneously and end up with the LED's to the left and right. My headlights have rectangle reflective domes. I installed the lights with LED's to the top and bottom and found the lighting was less than adequate. Once I moved the LED's to the left and right they light the road so much better. As far as the lights are concerned. The vehicle I installed these on is a semi-truck. I tried the brighter halogen's but the rough roads and rough ride of the truck would knock them out quickly. These headlight bulbs are brighter than the bright halogens and have handled the rough ride quite well. I'll be purchasing some for our cars.
