Super Bright Car Headlight Slim All-in-One Cree Chip LED H1 H3 H4 H7 H13 9005 9006 Lighting Bulbs Conversion Kit Hi / Lo Beam 80W 6K-8K H11 9005 9006 Mihaz H11

The following review is based on my personal experience, and it represents my personal opinion of this product/service. Therefore, please keep in mind that your experience might be different.The bulbs themselves feel quite sturdy and not cheap at all, the same goes for the little pigtails (igniters?). However, the little plastic white rings feel like they were made in a rush. They fit somewhat loosely on the bulb, and extremely tight or not at all in the headlight (to the point where modification is REQUIRED).That being said, I would suggest taking the rings off the bulbs and mounting them in the headlight on their own, and once that has been successfully completed, proceed to mounting the bulbs in the rings (otherwise, there is a high probability that you will strip the inside of the white plastic rings, and bulb will sit loose inside them).My vehicles use H9 and H11 bulbs, for high and low beams. These bulbs state that they are 80W, but the amount of light produced is much lower, light pattern in uneven and less focused than what I was getting from a pair of 80W Stark bulbs I had before these (the only issue I had with Stark bulbs was that they had a fan for cooling, which caused humming/buzzing, and interference with FM radio).
