Such great bulbs!

Looked all over the place for LED bulbs that didn’t flicker or give me error codes. Found these through a friend and they did the trick. Really bright and no error codes or hyper flashing. Their team was really great helping me find the bulbs I needed. Thanks again!

CANBUS LED taillight bulbs

Unfortunately I still received a hyper flash error message after installing the bulbs. I contacted Alla customer service. They did give me a couple of options to correct the issue with resisters. I declined and requested information for returning the bulbs. The representative was not pushy and very professional in honoring my request and providing the return information. I liked the bulbs but it was not meant to be used on my vehicle. Customer service was fantastic.

Works Great on Accord 2007

The product works well on my Accord 2007. It does not hyper flash but that’s because I installed a Signal Relay sold here on amazon which helps with that. The lights are nice and bright and definitely are better than stock halogen.
