The Stovebolt Site Forums The Shop Area The Electrical Bay 6 volt rear Led's Great, one issue though.

Yep, due to hard to see 6 volt brake/turnsignal's when the sun was shinning on them I reciently changed to these. Thanks for the link tclederman! They work GREAT.

The problem is now the pilot light on the turnsignal switch doesn't work. So I'm always wondering if the turn signals are working. After many confidence inspiring checks they are, but I'd still like the pilot to blink.

Still have the incandescence bulbs in the front, no other change beyond changing the tail light bulbs. No fast flashing at all.

Any thoughts on the why question and a possible solution are welcome.

Thanks, RonR

The original style flasher unit/can works off the current-draw by the bulbs. The LEDs draw far less current, so the normal flasher does not work properly.

There are 6v LED flashers but they are not common (and I have not tested the ones I got from Sweden/Norway (motorcycle application, I think). Some people do a kludge/work-around by wiring-in a few incandescent bulbes under the body (to produce the necessary currect draw).

I'll see if I can find a currect flasher, and will edit this later.

Maybe something like this?

Thanks for the link Tim. You may well have identified the problem, low amperage draw with the rear LED's. I'd considered that possibility but since the flash rate is still normal (due to the fronts still being regular bulbs) I don't really understand why the pilot light on the flasher switch isn't working.

hmmm, that flasher unit might not solve that problem

Double check the turn sig housing is grounding good to the steering column (or where ever it's mounted). The clamp on mine occasionly needs tightened.

I had considered that and sorta wiggled at the housing, no movement, no change. That said I'm now thinking that if I had a marginal ground all along, the reduced amperage with the LED's might not be making ground. Sounds good as I set in the recliner thinking about it. Will test the theory in the am.

Your suggestion that "marginal grounds" caused more problems with LEDs is exactly the situation that I have on my 1954 Chevrolet 6v Suburban. The original bulbs had gotten so dim that friends told me not to drive at night. I switched to 6v LEDs and the ones that work are much brighter than any of the original 6v bulbs. But, some of the LEDs do not iluminate, or, they are intermittent. I attribute this to bad grounds, resulting from the excellent epoxy primer and urethane top-coat paint. Bad grounds from good primer/paint.

On the 1954 pickup that is ready for finish painting, I will ream the lighting-fixture screw holes using "wire brushes/bits" made to clean screw holes. I will eliminate future rust in those holes by treating them with anti-oxidant stainless-steel grease.

A very good point Tim about the reaming the holes on "marginal grounds". I have a grounding problem and this could be the solution. Where can one find those brushes and the ss grease? Thanks, Steve

Here are some examples of wire-brush bits

I do not remember where I got mine, and what their sizes were.

I got some for hand-reaming and some for an electric drill.

I think this is a conductive anti-ox grease?

thanks Tim.. I might check my flaps
