next to the windshield reseviour for size purposes. Smaller than you think. The only ones that are smaller seperate the inverter from the ballast.
Hid bulbs are much larger than halogen bulbs. Try to see the blue, and youll see what the color is about. Its only a light blue colored bulb.
Nice aluminum heat sink ballasts.
I chose these over the cost leader which are xentech because of numerous bad reviews on xentechs waterproofing. So basically just reliability. Their youtube video shows them both underwater and xentechs failing.
same video showed me that they were all exactly the same brightness. The more expensive bulbs fire up faster and last longer, but here in 2012 even the bottom end bulbs are now awesome and fire up instantly.
These also have smaller ballasts That did not and does not matter to me at all. Our headlights have enough room for an xbox in there. BUT if I were to transfer these to fogs someday, having a small ballast on my bumper might matter a lot.
excellent quality. includes an extra male male cable that is unnecessary in our cars and just adds more connections that could corrode. You want that hella bmw connection straight to the ballast skip the chinese extension wire.
I used it anyway but will eventually go back in and pull it out.
I ordered 6000k bulbs the most common hid color.
If I had to do it again I would get 4300 or just white. the only difference is the bulb has light blue on it. So its easier to put some blue laminate on a white light than it is to try to put a white laminate on a blue bulb ( meaning impossible.) and a yellow laminate on a blue bulb now makes green..... basically a white HID is cool and versatile and a blue or purplle hid is permanently that color.
you want some yellow headlights someday or green? put on some laminate. The ones I got are sky blue as far as I know its impossible to ever make them yellow with a laminate.
took 1 minute to install.
bulbs have 0 startup time.
Much brighter than halogen but I cant measure for you.
required pointing my headlights up compared to before. I have no idea why but i suspect its lowering springs and the previous headlights were so dim I and the previous owner didnt care.
yours might not need adjusting at all.
