Tail Light Stuck on Bright.

Post by deafanddiabetic » Wed Sep 30, 2015 12:56 pm

Hey everybody,

I've mostly got the CA72 Dream together after an engine and transmission rebuild and a new COAt of paint. I'll post pictures when it's together!

I marked all my wiring harness leads before disassembly so that I could just plug and play when putting it back together. I decided to solder and seal all the wires to be safe.

My only issue is that my tail light is stuck on bright, or acting like it's "pulled". I tried switching the wires at the tail light brake lever switch, but that didn't make a difference either. Could I have gotten the two wires going to the tail light switched up?

It was working for a short while, like had it's normal running light, then I pulled the lever switch down and it went bright like it's supposed to, now it just stays bright.

Not sure what the issue is?

Sounds like the brake light switch is bad. Take it off and test it with a multimeter. See if the spring loaded plunger on the underside is stuck.

I'll give it a good cleaning tonight, it's looking a little worse for wear. The plunger moves freely but it sounds like there's a mechanism underneath it that might be getting rusty/stucky?

Definitely clean and test it. There isn't much below the switch that's complicated enough to go too wrong. The little arm below the switch is attached with a shouldered bolt, so I don't think it could get rusty enough to lock up, but give it a look too.

Plenty of used switches on ebay. If you want new and don't mind non-stock, you can search for non-Honda replacement, like this: http://www.ebay.com/itm/Emgo-Rear-Stop- ... 59&vxp=mtr Cheap at $9.95 with free shipping.

Wow, that's a great price, stock is never a concern for me.

I'll post what I find out tonight and see what comes next.

A good cleaning did the trick just fine. A spray of carb cleaner and working the plunger back and forth.

Thanks everybody!
