Motorcycle Head Light and Auxiliary Lights Adjustment

[@donalddavis7160]

I know it’s been 2 years since you released this video but this is exactly what I was looking for. You easily explained the process for adjusting the lights. Really appreciate this

[@tonysilva5558]

Great video and explanation, took my bike out for it's first ride last night and the low beam was way too high so I have some work to do before my next night ride.

[@JoseVargas814]

Thank you for this video. I used it to help me adjust my headlights, and I liked the explanations in the video.

[@dougandrews9052]

Great explanation! Thanks for your help.

[@gregoryolsson6668]

Thanks for the info. This was explained very well.

Does this take into consideration the weight of the rider and the compression on the suspension under different weights?

[@christianmachado3628]

Hello. Curious if your measurements take into account suspension compression under weight? Great video!

[@JM-xe1ul]

I’m also wondering the same. Did you get an answer?

[@Getting-On]

Great video, thank you.

[@TribeQuadQuest]

Thank you for the video. I just checked mine. the headlight is about 33.5 and at 25 feet I am seeing the light hit about 34-35. so slightly higher. Is this bad or will it do?

Does simply sitting on the bike change the heights on the wall? How much sag do you have when sitting it?

[@orbsurfer8195]

Ideally the lights should be adjusted while someone is sitting on the bike. The amount of sag is dependent on the type of bike, weight of the person, spring adjustment etc. You can get a rough estimate of the sag by using a zip tie around the fork up front pushed all the way down to the seal without sitting on it, then sit on the bike, get off the bike and measure the distance the zip tie moved.

[@Trotters79]

​@@orbsurfer8195 It is also dependant on weight distribution. If the rear drops further than the front when you ride, the lights will raise and you risk the lights points upwards (if they aren't properly adjusted while sitting on the bike).

Any tips on adjusting duel low beams, similar to your spotlights. I want to get most width as possible from my double low beam setup

[@orbsurfer8195]

mark a center line on a wall - then mark an equal distance from the center line to two additional vertical lines - one on each side of the center line - as for the distance to the two additional lines, it will have to be an adjustment in progress - start with 12" /30cm and see if it is too much or too little after a ride in the dark, then change by 4"/10cm at the time... Sorry I cannot give you an exact number - I do not know if you want the lights to perform like cornering lights on many cars, or just to generally light up the edge of the road.

[@banzobeans]

How did you come up with the reference values? Is this the same for every country? I‘d be surprised.

[@geroldmiller8983]

U don't need to make sure your pointed square to the wall for left and right?

[@tyronevincetamayo5104]

What would happen if I use 50/55watts H4 to my 150cc motorcycle?

[@donaldallmon6804]

You'd have a light!!!

[@420BLUNTLEY]

Dude I don’t think you need a fucking measuring tape for this lol. Just point them ahead and down.

[@Trotters79]

To do it properly, you need to measure things. You can always eyeball it, but then you run the risk of not having enough light far enough ahead, or you risk that your lights are annoying for others in traffic.
