Side marker bulbs?
Can anyone tell if the small bulbs in the side marker/blinkers lights on the front fenders and on the bed should be dual filament or single. I thought they would need to be dual, as when the lights are on at night as running lights the second filament would be needed to blink brighter for turn signal use.
Also the bulbs and fittings in my side markers are the push in type the same used in the instrument panel. ![]() Hope i've described this properly. Thanks

Re: Side marker bulbs?
I think they are just a 194 single element bulb.

Re: Side marker bulbs?
Thanks 71stub, are your bulbs the same type as mine? the reason I ask is that the parts stores only seem to stock the metal cap twist in type for side markers.

Single element but the fronts blink and the rear don't when turn signal is on. NAPA has them and Oriley's, Advance Auto.

Re: Side marker bulbs?
Take the back ones loose and see if the grounds are good. I have the 71 model deluxe and my back side markers have never flashed.

Re: Side marker bulbs?
The only rear side marker lights I've seen flash had been rewired to flash. I am 99.9% sure they didn't flash from the factory.

They do not flash from the factory. My Dad had a 72 lwb Custom Deluxe new and uncle had a 72 Cheyenne new (brother has it now). Neither truck rear side lights blinked.

Re: Side marker bulbs?
This is correct, the rear side markers never flashed from the factory... not even required to by todays DOT standards.
The front, some of them flashed, some did not. Your 4 ways not flashing... try swapping your two flashers around, one for the other. They are the same part number unit, so if swapping them fixes it, you know what you have to do. And finally, for the original question, the above is 100% correct, single, not double. When the parking lights are on, and the side markers flash, it isn't brighter than running lights, it turns on and off. 194 bulbs are the correct number, in american cars they have been the norm since the late 60's in the inst pannel, and are still used today, but not as frequent as back then.
