Electric Bicycle LED Headlight and Taillight 12-80V Super Bright Built-in Horn Electric Bike Headlight with Switch (Bulb 4 (Headlight with Bl ue-teeth)))

The kit is complete except for installation instructions. Once determined the wire connectiins it was very simple to install. The yellow wire from the switch goes to the positive battery and the black from the light is negative. The green and red wires from the switch connect to light’s green and red wires. Red to red and green to green. This was reversed in the prewired terminals when I received the kit.The horn sounded when the light switch was turned on and the light flashed on when I pressed the horn button. I simply extracted the female pins by pressing in on the retention tab and reinstalled them so that it was red to red, green to green. Green is the light, so a tail light positive will connect to green and the tail light will need to be wired to the battery negatve terminal.The light is not overpowering and has a greenish halo around the fairy narrow beam. I would prefer a cold blue white light and a brighter, wider beam.It will work well for my needs and the lower wattage will conserve battery.

I purchased this for the electric horn. The horn is quiet, good for alerting pedestrians on a bike trail, but I don't think it would be heard by a car that is coming your way.The light seems quite bright, but I haven't ridden at night yet.The Bluetooth speaker is nice to have, though it is hard to hear if it is windy outside.It would be nice if the type of connectors were listed to make wiring easier.

I installed this headlamp just over 48 hours ago and it lit up the road so well that I had to check over my shoulders a couple of times to make sure there wasn't a car following me because the light lit up the road that well.I made one fatal mistake, however.I put Loctite on the screw that goes through the base of the lamp where it attaches to the bracket, thinking that it would be extra secure and that the light wouldn't drop down due to loosening of the screw and nut.I WAS WRONG.I knew you shouldn't use Loctite on plastic, but had no idea that it would cause any plastic surrounding it to crumble to chunks of debris within 36 hours of exposure.I don't blame the manufacturer of this light. It was clearly my fault after searching the net for "Loctite and plastic".Just ordered another of these earlier today, and won't make that mistake ever again.:(

Model: Bulb 1 with hornThis headlight was installed on a 48V eBike. It puts out a reasonable amount of light but I would have preferred it to be brighter. The horn is loud enough for my needs.The horn / light button switches were reversed, so I had to swap the wires to them. But for a more customized installation I didn't use the provided switch. Instead I installed a better quality handlebar switch that also controls the bike's turn signal lights: Kawell Switch light turn signal Switch dirt bike honda ktm suzuki kawasaki yamaha sport motorcycle universal 520 450 530 500 250 wr wrf xr 600 650 dr drz 7/8 handlebar hi/lo dirt bike conversion It's a good headlight. Not great, but good. I give it Four Stars.

I have a 48v e-bike. I installed the light and used the horn like 10 time in a row and it started to smoke. Not good. The horn and Bluetooth stop working at this point. The light still work; however I return it because of broken features.So thinking it was something I did I order an other one. This time I isolated it. Everything was working fine them I switch my high beam on, and the Bluetooth stopped working along with the horn. No smoke this time.Long story short is this thing is junk. I do like the light. The case is metal and the light is bright for as little power it pulls. The switch is plastic junk and will break in a crash. The Bluetooth sounds bad when it was working.Sad times even with the bad sound it would of allow me to hear directions from my phone. So this is going back and I'll order a plain light for my low beam.

This is the best light for nighttime ridersAwesome product and customer serviceThe best, I highly recommend this !!!!!....

Integrated into my electric bike ok but found they red and green wires swapped in harness so horn worked with light button and visa versa... i fixed it myself.They need better quality control.

Cheap casing ended up having to tape it together and re-sodering the electrical led wire came undo on first ride. =/ after my repairs it still works also the horn is very not loud idk what other people are talking about big let down on the horn. The light is very bright
