I have a 1981 Honda GL500 Silverwing.
Could someone tell me which bulbs are correct for rear turn signals? They look like they have a screw holding the bulb in place.

Per the General Information section in the GL500 FSM: 12v-32cp No. 1073.

I ordered those and they were wrong. Mine are small and seem to be screwed down. I will have to pull the bulb out come morning. Thanks for the response tho. Greatly appreciated.

From what i know 1073 is just a bayonet type bulb.
Yours look non-std.
I dont own a GL....but looks aftermarket/conversion to me...

Yes, non stock. Do a search for the number printed on the bulb.

Try taking it to Autozone or one of the other auto parts stores.

As per #10...just the local auto parts store should give you something that works.
In some situations, depending on wiring you may need to replace more than 1 bulb if there is not an exact match

That bulb is listed as being 4.9 watts, whereas the original lamp is 21-24 watts.I don't think that will be bright enough for a turn signal bulb. Can you find a higher wattage bulb in the same form factor?

Those bulbs are not bright enough for turn signals. These bulbs might fit the light socket but are not meant for or legal for use as turn signals or brake lights. If you can’t source proper bulbs for those turn signals I would recommend replacing the turn signals with ones that you can source the proper bulbs for.

The 194 bulbs are brighter than you’d think. In automotive applications those bulbs are commonly used for side marker lights and some makes and models utilize them as part of the signal in addition to the primary bulb that’s on the front/rear of the vehicle.

At the very least, buy one and see how bright it is with the lens on. If it’s actually not bright enough, you’re only out a couple of dollars and can keep looking.

I got a pack of 2. It said it was for road use. They are plenty bright enough for me.
