Halogen turn signal question

Post by Fauxfidelity » Fri Mar 30, 2018 7:09 pm



So I have some stock halogen bulbs in my stock rear turn signals on a 75 gl1000. What I am noticing is that they are not “running lights” like the front turn signals. Also that when the turn signal is turned on the light is not as bright as the front, with only one of the filiments lighting up (the filiment that is used as the front running light). Is this a wiring issue, or is this intentional? Thanks guys.

Never heard of halogen bulbs for turn signals. Am I reading it correctly you have 2 filament bulbs in the rear? The rear should be a single filament bulb, like 1156.

Totally meant filament! And no, there were double filament bulbs in it when I got it! I will be changing those out and seeing if it works. Thank you!

As stated by Dave, only the front bulbs are running lights and indicators and have twin filament bulbs. The rear use a single filament bulb, sounds like you have a twin filament bulb in there, normally you can’t put a twin filament bulb in a single filament mount, they are different to prevent this kind of issue!! If someone has forced a twin filament bulb into the rear indicators then you need to change them for a single filament bulb, or else someone has fitted front indicators in the rear of your bike and connected up the wrong wire, the rear should be using the high power 21watt filament NOT the low 5watt running light filament. I would get the correct bulbs first and see if they will fit in the rear indicator, if they do then everything is good, if they don’t fit, then I think someone has modified the rear indicators and you might need to swap a couple of wires.

A quick look at the socket should reveal what bulb should be in there. Twin filament bulbs have offset pins, single do not (in most cases, certainly these Hondas). I have seen all manner of bodgery, so would not surprise me that wrong bulbs may reside therein. A PO may have swapped sockets, this can be done fair easily, then the wiring needs slight modification (run a lead from taillight feed).

Note, too: there are some lighting accessory boxes that DO allow the rear to be running lights as well (I have such). These run the OEM 1156 bulb at lower voltage to mimic a running light. This one also does a light show when you hit the hooks to better alert the idiots behind.

P.S. Lower brightness is often a ground issue. Make sure the grounds are clean and tight.
