mnmkiller I run with my high beam on in the daytime. Wouldn't even think about running with no headlight. That's insane! Mike '89 vn 750

Foxhound You just want to be able to turn the headlight off and back on with a switch right.

I will try and do a switch mod on the other lady and when I do I'll do pics and a writeup.

Crobins365 Asaracho, did you do a mod yet? SOrry I forgot to post pics - that's what happens when I leave town for work; I get back and forget everything meaningful in life. I'm not sure that the mod done to my bike is according to hoyle, but I'll post some pics today and then folks can make suggestions about how it could be done differently (plus, in case mine fails when I'm on the road, I'd like to know what I need to do to get home safely!).

norsseman Would be great if there was a posted mod for a headlight on/off switch with pic's for us mc riding dummies.

jetboy i lived on a country road for 8 years of my motorcycle/scooter riding-- and i enjoyed the no light ability

1. i would run without the light on during the day to conserve battery power. why? I rarely met anyone on the road, and the danger was not to be mitigated much by a light-- its the blind turns all up and down the road so i always rode the line ready to get the hell out of the way. i was once almost hit by the school bus, to this day im pretty sure they didnt see me. - that was on my scooter with the light on(no turn off option)

2. at night deer cows and sheep love to run in front of your light, they wont get off the road(sometimes deer love to just stair into your light!)!! but if you turn your light off its less frightening and they will either stop so you can go by, or come to their senses and move to the side.

3. its actually a much stronger signal to turn off and on the light than to just go low/high beam--ifn't you need to signal someone -

Sky Rider I think the main reason for the automatic cut over to the high beam if the low fails is for daytime riding when you wouldn't notice if your headlight wasn't working. Night time is a no brainer.
As far as riding without a headlight, there are people here who do it but the difference between a lit bike and a dark one is very different. The headlight on gives us much more chance of being seen than without.

mt700a1 Hi,

I wired a switch for the headlight about 4 years ago, after the headlight cut out and left me literally in the dark on I-95 on a Friday night.

I traced the problem to the reserve lighting unit (RLU). I bought an standard automotive relay (~$4) and a switch ($2) rather than replacing the RLU. Headlight draws a lot of amps so you should use a relay. Relay can be powered by anything that is "live" only when the ignition is on, so that the headlight turns off when you turn off the bike. I could have wired it so it's always on when the bike is on, but I didn't. The reason for installing the switch was so I can turn it off when I'm stuck in traffic on a hot day. As we all know, running the fan for extended time at idle kills the battery. By turning off the headlight (55W), I can get sufficient voltage to prevent that.

If your RLU is fine, I'd suggest that you install a switch for the RLU wire that powers the headlight relay. I think it was a blue wire. Check the wiring diagram. If you can't find it let me know, I can look it up. Again, you don't want to pass the large current required to power the headlight directly through the switch. Switch should turn on and off the relay, and relay does the switching of the headlight current.

It is a good idea to run the light at all times but it sure is nice to have an option.

curtis97322 Take a look over at https://www.vn750.com/forum/showthread.php?p=32057 - the headlight is cutting out and it seems that moving one wire will take care of the problem. You could run a switch down to there and keep it clean/ easy to undo.
