Review on 💡 MZS H4 LED Bulb: 12000LM 9003 HB2 Conversion Kit for Wireless Plug-in, Fanless Design, 6500K White Light - Pack of 2 by Marcus Dorgham

Received and installed on my 2003 first generation Prius. While installation isn't easy, the main culprit is the engine compartment, not the bulbs, which are only slightly larger than halogen bulbs. However, due to the larger diameter of the lamp base, refitting the dust cover was a problem, so the 4 stars are mainly due to the lack of a warning in the marketing jargon. They offer a contact in the installation guide for a universal dust cover that I can use. I put my boot on after heating it up with a hair dryer to stretch it and some petroleum jelly. Significantly better vision than the halogens I replaced. I just installed it so you don't focus on longevity.
