2-Pack of Nilight D4S HID Bulbs - 6000K Diamond White Replacement for High Low Beam D4S HID Headlight Bulb in 12V Cars Review

I can't say how long they will last but they work great for the 2014 Mazda6 Grand Touring. A big upgrade over the yellow bulbs.

Easy installation on a 2010 Lexus RX350. The 6000K bulbs are slightly bluer than the current ones. I've never used gloves to install lights, but in this case I used the gloves that came with it.

I wanted to wait a while before writing a review as this type of tube is notorious for premature burnout. I've driven about 50,000 miles since purchase and they still shine as bright as ever. My friends and I didn't think they would last. I am very happy!

The lamps are really high quality and packed in a neatly organized box with everything needed for installation. I wish the bulbs were a bit brighter, but I'm definitely happy with the product as other HID bulbs I've bought in the past have been weaker and burn out easily.

I was originally told that 1 HID bulb for my car would cost $180 so I jumped in here and found these and decided to give it a try, they fit perfectly and are great super bright . Absolutely amazing deal and product! Can't comment on durability yet, but I'd spend $30 for 2 instead of $180 for 1 any day!

I bought them because the reviews said they work well and fit my 2011 Lexus IS250. Fits well, and while tedious, installation is relatively easy. However, after installing them, I wondered why they weren't bright at all. It only glows about half the distance my original bulbs traveled and is very unassuming. Maybe they'll find a replacement soon.
