Can someone explain light bar install?

Recommended Posts

Let's say you have a street legal bike with no power draining accessories installed and want to add a small yellow light bar above the headlight to cut through the coastal fog and increase visibility on the street, and dirt/dust when following buds in dry offroad conditions.. 

What are some of the simpler ways to wire one in? Straight to the battery with an inline fuse?

Tap into the headlight wiring?

Something different entirely?

How about turning it on and back off again independent from the bike starting/stopping?

I'd like to tackle this but have surprisingly found almost no how-to's online.. only how to wire up a big ol light bar to a car or truck through the fusebox.. not sure how much relates but figure its gotta be pretty straight forward. Thanks in advance

As simple as is can be there are considerations to be taken in to account. 1. Current draw of the device compared to current capability of the charging system. Do not draw more amps than you can produce also consider the draw of the OEM components. 2. I would typically not recommend taping directly into existing wiring to pull additional load for accessories. Use a relay with fused connection to the battery for your power source. The trigger for the relay can be any existing switched source or an independent switch.

Pretty simple. Get some 12 or 14 gauge red and black wire from Oreilly. You can probably buy some that has both wires in a tube jacket. Use crimp on circle connectors screwed directly to the battery. At the battery put an inline fuse holder, the two tab type with a waterproof cap. Wire that inline on the red, between the positive battery post and the red wire going to the front. Pull the red wire up to the handlebars and wire through a switch like this one https://www.amazon.com/Hanperal-Motorcycle-Waterproof-Handlebar-Headlight/dp/B06XTB328S/ref=asc_df_B06XTB328S/?tag=hyprod-20&linkCode=df0&hvadid=309804735743&hvpos=1o2&hvnetw=g&hvrand=7159869733346300797&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9029138&hvtargid=pla-568563775906&psc=1

Take the black directly to the light. Hook the other wire of the switch to one side of the light, the black to the other. Zip tie it to the other head wires, leaving enough slack to turn. 

A relay is not really necessary as the light will not draw more current than the switch rating if you do your homework. Don't oversize the fuse, see what the amp draw on the light is and add about 25% to get fuse size.

Additionally for seeing in fog you should mount the light bar as low as possible.  The reason is the light  from the bar will mostly reflect directly back.  The lower the light the less reflected glare back to the rider. This is why most cars and SUV  fog lights are mounted very low on the front of the vehicle.   The narrower angle the light pattern the better for fog, rain, and snow, to reduce the reflect, back scattered light.
