Very well made product.

Normally I go with Superbright leds. I have never heard of Alla. I did some research and found more positive than negative reviews for the bulbs I was looking for. That all being I am very impressed so far with the bulbs that were purchased. They are very bright but clean at the same time which gives the interior of the vehicle a nice look. I also ordered strobe reverse light bulbs. They are also very bright and look very clean in the housing. Very easy to install. Plug and play. The only thing that was interesting and by no means an issue is the post is a little thicker then the original halogen bulb. Disconnected the battery then utilized a small flat head screwdriver and pushed up on the housing of the socket and the bulbs went right in. They are snug as they they should be to minimize movement. Overall I am very happy with the purchases. I will be ordering the festoon bulbs for trunk and and the license plate lights very soon along with the headlight bulbs as well.
