Passing lamps on with high beam?

20710 Views 27 Replies 19 Participants Last post by  wkohn
Any one know how difficult is to make the passing lights stay on while the high beam is on. I cannot figure why most all vehicles are set up this way, on a open road needing your high beam why disable the passing lamps which could help light things up? :huh:
I went through the same problem with my jeep but I installed a jumper in the relay that allows the fog lamps to stay on with high beams. Can the same be done on a 05 heritage soft tail? Thanks for any help. Chuck

Sure can. I just did it yesterday on my Road King Classic. The hardest part was getting the trim ring off and back on around the head light. I used the attached diagram.
yup that diagram worked for me too........very easy mod.....well worth it
I felt the same way when I installed my passing lamps on my 92 Dyna...
I just took the positive wire on the Passing Lamp harness and sliced in enough wire to run back to the relay/ Circuit Breaker panel and tied in on one of the breakers... Now |I have full control of them.
All the best,

I'd been wondering that myself. Thanks for the diagram!

Most State Laws require passing lamps on with low beam only. (found that out the hard way)

Most states wouldn't like my low beam with the passing lights. Everyone flashes me cause they think I have my brights on. Then I flash them the brights.:D
Thanks for sharing the diagram. I always ride with my passign lamps on and am undecided on whether to modify them or not but am now armed with the know how.

People flash me and get pissed if I am behind them but at least they know where I am, right?

Its must not be COOL to run with all my lights on over here, but the irony is that I still have people turn in front of me, pull out in front of me etc. (WTF??)
The reason why cagers flash you at night with the passing lamps on is that they are aimed straight ahead verses slightly down like the headlight is. Comes from the factory aimed in that manner. If you look in the service manual you will see the adjustment procedure states to line them up "straight ahead with the center of the main light beam even with a horizontal line drawn on a wall 25 feet away."

I get flashed at night as well. I have often thought to aim them down some, but that would make them less noticeable during the day.

Ah but I have also put in brighter bulbs.:brows:
Does that diagram work on a Heritage? I don't have an accessory switch.
On the Heritage, you will need to remove the Yellow wire that runs to the passing light switch and conect it with the Orange w/white tracer wire that is located at pin 1 of the plug for the head lights. This is the accessories power, it is used for all running lights.

What he said. Sounds just like the FLHs minus the switch.
side note

On European and other export Harley's the passing/fog/driving lights are wired to be on with the high beam and not with the low.
I have the diagram to make the modification, my question is on an EG are all the wires in the headlight housing or the inner fairing? or both? Thanks.

They should be in the headlight housing just like on my Road King Classic. Double check your shop manual to be sure. Remember the trim ring is a pain to get off and back on. At least it was on my bike.
I made the wiring change on my 03 eglide.
I thought I followed the instructions from the rustler web site and they stay on for high and low beam but I can't shut them off with the switch on the fairing. They do shut off with the key so its not the end of the world but if I switch on ignition to acc. the passing lights are on. I like listening to the radio while I work on or clean the bike and the light will run down the battery. Anybody have any ideas?

You do know that the headlight will aways stay on if you turn the switch to the start position. Turn it to accessory and the lights shouldn't come on at all.
The wiring diagram is in your shop manual. I don't recall what the colors are, but you cut the feed going to the passing light switch and connect the switch to the power going to the handlebar headlight switch. That way, you have power going to the switch all the time (when the key is on), and it is fused thru the headlight fuse just as it was before.
All connections are in the headlight nacelle (touring).

On an EG, all the wiring is behind the outer fairing. Just take it off and everything is right there. No wiring in the headlight housing on EG's.
