4 inch Universal Motorcycle Led Driving Lights, 45W, Running Lights LED Work Light Bar White Hi/Lo Beam Motorcycle Lights for ATV Truck E-Bike (1 Piece)

This little light is very well built, I took the reflector off and the guts consist of a single MCPCB that is well bonded to the body of the light. Good heat transfer and long LED life are expected from this simple well thought-out design. I have two of these lights, one on an ebike, and another on a 50cc scooter. The light is wonderfully overkill for the ebike, letting you see even small road imperfections. On the 50cc scooter I would rate a single one of these as just good. Going over 50mph would lead to out riding this light, and in the rain it isn't strong enough to deal with the diffraction. Having said all that, it is 100 times better than the stock headlight on these bikes, and only limited by its power, the beam shape and cut off are perfect. On a small scooter you do not have the power to run something brighter anyhow, so this is the best compromise you can make. I am considering adding two of these to my car as fog lamps, and think they would work perfectly in that application as well.

I needed a replacement headlight for my Engwe M20, but didn't want some awkward oversized motorcycle headlight and I also didn't want to run an external voltage regulator. This light is not only the perfect size for a typical E-Bike, but it is capable of running directly off battery voltage. I was able to wire the low beam into the stock headlight circuit and add a secondary switch to toggle the high-beam. As in some other reviews, I measured the wattage which was around 20W with low beam and 30W with high beam. My unit does not seem to heat up readily, and the metal case certainly helps with keeping it cool. The headlight pattern is also acceptable, with the low beam having a sharp horizontal cutoff. Unfortunately, I needed to design an adapter to fit my particular style of fork mount. I made up a 3D printed shim to use the two M4 mounting screw locations and convert it to a single large 10mm bolt. If you're interested in this adapter, search for it on the Printables website.

Fantastic light with lost of throw that is well defined. Low is a half dome with clear horizontal line and high adds a squared center focus making it really bright compared to incandescent bulb. Used in a Honda XR250 in original housing. Made a bracket for same hole set up and added a switch for high beam to control. Really happy with set up.

Shopped around for something to add on my KLX140. This little light fits very well. I had to customize the mount a little but worked perfectly for what I needed. Pretty bright for what it is, the hi-beam is ok but not super bright. Works as advertised, solved my problem.

I have an ongoing project to "snazz" up an electric tricycle to use as comfortable short range transportation at times when my wife needs the car and I need to go somewhere local before she gets back. On Saturdays, weather permitting I even ride it about 10 miles in the early morning hours to attend a breakfast meeting of our Amateur Radio Club. The single small headlight that came mounted on the trike was pretty much just for show and was totally inadequate for any serious night/early morning travel so I added a couple more (also had horns in them) which made it a little better but still marginal at the 20mph max speed I run most of the time. I was browsing Amazon looking for a better headlight that not only was much brighter but also had "High/Low" beam capability, run on 48 volts and have relatively low current draw. when I came across this one for a very reasonable price so I ordered one. While waiting for it to arrive, I added a handlebar mounted High/Low beam switch to the handlebar close to the left grip for easy access. When the new headlight arrived I was able to mount it directly in place of the original trike's tiny headlight, used the original 48V power and wired up the High/Low switch. Now, there were no instructions that came with the package, so you have to get them from the seller's listing on Amazon. The black wire is common (negative), the yellow wire is "Low Beam" positive and the red wire is "High Beam" positive. Pretty straight forward for most people that are DIY persons. If not, find some professional or knowledgeable help if you can. Once I had it wired and working, I took it outside to align the high/low beam positioning and try it out. Quality of the light assembly is excellent, it works well on anything from 12V (my initial test voltage before install) to at least 48V (highest I have available though seller claims will work to 80V so it's pretty versatile). It also comes with several ways to mount it and the proper hex wrench for the provided bolts. I never ride in the rain as this trike's electronics aren't waterproof but the light is well sealed and ought to be no problem even in a driving rain if you should get caught in one. All in all, I can definitely recommend this and wouldn't hesitate to buy it again.

This is exactly what I've been waiting the past 10 years for. The light pattern is spot on for normal driving (at least from bench testing, update coming when it's drive tested), the low beam has just enough uptick to light signs and improve visibility without being blinding or inconvenient for oncoming cars, and some additional foreground lighting. The high beam is aimed correctly aligned with the low and looks like it should have decent throw. Power draw is pretty much on spec with the low beams drawing about 18w (1.26A @ 14.1V) and the high beam which is both lights drawing about 28w (1.99A @ 14.0V), which is still pretty low for the light output you get. I did notice that after some time on high the draw ended up dropping to about 27w (1.9A @ 14.1V), it could have been thermo regulating, or just stabilizing. I did a very basic heat test, and it ended up at ~155F in ambient temp of 68F after a runtime of 10 minutes on high. Perfectly acceptable, especially in a vehicle mounted application where it will typically receive air cooling. The mount seems perfectly sturdy, and the hinge mount allows for upside down mounting. It does come with a bar mount. The light itself is also tapped for M5 bolts on the side, allowing alternate mounted options. Overall I'm incredibly pleased with how this performs and is built. It's the only light I've found to date that has a proper beam pattern in this size and power, and I've been trying lights for almost 10 years now. We'll see how long it ends up lasting, but I have high hopes.

Bright little headlights for the money. I have Lux readings comparing these to SAE DOT fog light pods and these are brighter but don’t have as narrow a beam. I knew this going into it but wanted a decent cutoff fitting a 2.5x5.5 space and these will fit no problem. I’m replacing a 3” DOT SAE cube light in my 87 trans am as I’m hoping for more distance from these and to fill the OEM bumper openings a bit more. Amp wise these pull alittle higher than what’s stated which isn’t a bad thing but they do get warm quickly. 1.22amps @16.4w on low and 2.25amps @ 30.1w on high beam. I provided output shots of 17ft from a garage door and the narrow thin beam is the SAE DOT fog which works well for its purpose they are only 13w and pull 1.05amps. I think I’m going to wire these mini headlights for low with fog switch and add the highs with my high beam or wire them separate so I can turn them on or off independently. Hoping they swap right out with minimal mods. Won’t have longevity as I just got them today but will update if something happens down the road. Seems like a good buy and they are pretty tiny… I wish they were about 1” longer and a 3 lense setup.

Light is amazing. Plenty bright for my electric motorcycle. Looks pretty waterproof and never had an issue riding in the rain. Has a good light pattern too.
