Review on 🔆 High-Performance DMEX D4S Xenon Headlight HID Bulbs - 4300K - 35W - 2 Pack - 66440 42402 42402C1 Replacement by Matt Heringer

So far so good, a little nervous after installing both lights and waiting for the review. In fact, there is no difference between this set and the original. Good, bright, no problems so far. Let's see what time will tell, but that goes for any electronic part. The OEM lasted about 5 years on a Mazda 6, I have the same OEM infinity type bulb which lasts 6 years. Let's see how they compare. Well price wise if they last more than 18 months then this is the best deal as the OEM is over $170.
