*This bulb is designed and manufactured to work with CANBUS related vehicles, but we must stress that some vehicles, no matter how CANBUS friendly the bulbs are, they will always throw up errors on the dash or cause the bulb to flicker. If this is the case with your vehicle then a resistor kit is the only solution for you to enjoy these LEDs. Please see our ‘Accessories’ section for our simple and effective CREE LED resistor kit solutions.

I ordered a pair of these in amber for a 2011 Audi A4 B8 Avant (with halogen rear clusters), they have an excellent brightness and colour, look much better than the stock halogen bulbs. One of the 2 is occasionally giving an error, but this seems to be normal on this car (pre facelift Audi A4 B8, facelift don't have this issue), will be looking to add a resistor in shortly.

Simply brilliant! In two ways; brightness and quality. I have replaced indicators, side, brake, fog and reversing lights on my Volvo S80 Sport V8 4.4l AWD. What a difference it has made in brightness and activation response time. The only extra thing I had to fit was the 50w resistor kits as the CREE bulb internal Canbus was not sufficient for the Volvo and the bulb failure warnings came up. However after fitting, all gone! I'm a very happy chap with these bulbs and others from the CREE LED line of bulb replacements. Definately no mistaking my intentions and "being seen" now! Fully recommend these CREE products as they are second to none! Go ahead... do it, buy some and you won't be disappointed!

These are excellent bulbs with no canbus errors on a Mercedes W204. I am in the process of upgrading all my external bulbs over the next couple of months. I opted for the Cree LED 50 watt for my rear indicators as these give off a very bright, clean and instant light signal which I consider an essential safety upgrade (particularly for driving on motorways). Highly recommended LED Cree bulbs and Horizon is an excellent supplier with generous warranty.

There are loads of cheaper bulbs out there, the problem is that the quality is pants. You can buy 5 sets of cheaper ones and you'll end up with errors, dull bulbs or broken connections - you may as well have just bought some decent ones in the first place. These LEDs are absolutely spot on, they finish off the look of the car and give it the premium feel it should have had from the factory (I'm talking to you Audi!) They're well made and come with a guarantee - you can't go wrong.

I have look for a long time for LEDs for the turnsignal but there so many on the market with no quality. So i see this LED at Horizon LEDs and i order them i a can say they maked me 120% satisfied. That little lamp could shine so bright i could never belive until i tested it. The best LEDs on the market for sure . https://www.horizonleds.co.uk/index.php?route=product/product&product_id=323&secumt=I3RhYi1yZXZpZXc=
