No running light

[HawkGEye]

Hi there,

Thanks in advance for the advice! My running light went out last week. It did suffer a drop onto grass outside a friend's place just prior to that. I checked the bulbs, they're fine. If I flip the orientation of the bulb 180 degrees, the bulb lights up. But obviously, due to the way the pegs slot into the socket, it can't stay mounted in the reverse position.

I did a search and found some wiring info that seems a little greek to me. I'm probably gonna haul it over to my buddy's house (he's been working on Hondas since the 70s) but I'd love to have a good idea of what I need to do before I bring it over there.

Thoughts?

Thanks!!

Are you talking about the front marker light/turn signals? If so, those bulbs have two filaments and swapping the poles only lit up the one that isn’t burnt. Just replace the bulb with a known hood one.

if you’re talking about the rear marker lights, they only function as a turn signal.

Yes, you can't always tell if a bulb is bad just by looking.

If it lights up when it is flipped then it would stand to reason that the low watt filament is indeed blown.

Two blown at the same time is a little unlikely but more likely than you'd think.

If the circuit wasn't working then flipping the bulb wouldn't cause it to light up.

They both work as a brake light, just not a running light. So this would seem to indicate the low-watt filament is blown?

69Falcon The tail light is what I was referring to.

Yes, by this AND the fact that when you clock the bulb 180° off in the socket it lights up.

This is greatly appreciated. New bulbs on the way!!! Thank you ParcNHawk !

Pro tip: you can also use 1157A bulbs. They are colored amber. They still shine red through the tail light lens but are often on sale.

I e also used some led equivalents, which are brighter than the stock ones.

Lights came in and are installed. I have a tail light again! Thank you, folks!
