I loved the lights

I love Auxbeam products. Very clear white and amber lights with clean switches. They are super bright, after a year they are still extremely nice. They are NOT error free so you will need resistors to stop hyper flash. They are well built and fit the sockets well. I like the price point and have used these exact builds in 3 different vehicles.

Got the resistors it recommended, and one white lights already burnt out. Blinker part still works. Sad. Barely a month old They sent a free replacement, so changed my stars. If lights keep working after replace, I'll give 5 star. Seems to be working correctly. Very appreciative of the company sending the replacements. 5 stars

Excellent bulb. Super bright and the switchback function is perfect for using a clear lens and still getting the amber turn signal color. Flips from white running lights to amber turn signal lights when turn signal activated. I did experience a problem with one of the two bulbs having issues with seating in the socket properly, but a quick email to support and they sent me a replacement, which works perfectly. I used these to replace the standard incandescent 1157 front running lights/turn signals on a 2007 Honda VTX1300S motorcycle. Much brighter and should last a lifetime. I also replaced the lens cover on each with a clear, which I think looks really nice with the chrome.
