I only used the housing and the front lens, not the light bulb.The lens is plastic. But It's worked.Finally got this fully installed after some struggle. Works as advertised and looks great. Beware that wiring instructions in the listing are wrong. Actually, blue is for high beam, white is for low beam. As indicated, brown is for Halo and green is for negative. Getting the bolts to go through all the holes and into the threads when using the grill is a real struggle but definitely doable. Be aware that the final assembly the grill is offset from the lens glass by about 1/8 in or so. As someone else commented, the bulb is not standard. As an led, it should last a long time, however you cannot replace it without modifying the light housing. Since there are three bulbs inside ( high, low, Halo) but my switch is only high, low, off, I wired the Halo directly to the power (after the fuse), so that when the bike is on the Halo is on. Then I wired the high and low bulbs to the high and low of the switch.Looks great but the bracket it came with is intended for fat forksThe mounting hardware is very sturdy and only took about 15 minutes to bolt on. The light doesn't move at all when riding. This doesn't have an HR connection, so I had to cut, solder and heatshrink the connection from my previous light. Unfortunately, the this light is not very bright, even on high beam. Not a problem for me, as I'm hooking up driving spotlights to my running lights today, but it's something to keep in mind.Really only purchased this to make a tracker bike of mine street legal with a headlight. Metal is thin and the 'universal' brackets don't work worth a crap, they're horrible. They slide into each other on one side to make a hinge and then one bolt on the other side holds it together, super sketchy and didn't fit my forks at all. Bulb isn't very bright, which to be fair; isn't what I bought it for. Due to the quality I'd probably skip on this.I had high hopes for this headlight as the reviews seemed mostly positive. However, now that it's finally on the bike, and I tested it at night, it's far from effective to provide enough light to ride at night safely. Not to mention the LED itself is not a standard size, and the lens would probably diminish the effectiveness of a bright LED anyway.I was able to adapt to my ebike and operate through my controller with a LED light added. Works great and looks goodVery easy to install, a bit smaller than expected
