I ordered these in red to replace my stock rear foglight halogen bulbs, and man - what a upgrade! They respond immediately, with a clear bright red color, and is extremely visible even from far away. I was a little concerned about the length of these LEDs, but they fit perfectly into their housing and socket.

Excellent bulb, quick delivery, and significant increase in brightness over the standard H21W reversing light bulbs in BMW320i Touring (2016 facelift model). No issues with flickering, errors, or re-coding, merely a simple bulb change that worked, and took less than 5 minutes, literally, to complete. Recommended.

Excellent product in that it worked first time on an Audi A5...usually led's throw go up bulb errors or cause havoc.

These are great lights. They can be seen far away in bad weather and really complete the look of the Audi A5 front end with the LED DRL's. There are no errors or codes with these lights so don't worry about that. These lights are very bright and crisp and look factory which is the exact look that I was going for. Horizon was a great company to do business with as the product came to me in less than a week and that is impressive being that I live in the US! I will never buy from ebay or those Chinese companies again. This is the only place to source LED bulbs!

Such a great upgrade compared to my old fashioned halogen signal lights on my new Volkswagen Golf 7 Highline! Very bright and fitted perfectly in the headlight. I looked everywhere online for LEDs but Horizon had the only ones with 50W output, very rare! Fast delivery to the Netherlands by the way. Will definitely buy from Horizon again as soon as i figure out what else to change to LED.
