I am keeping my car 6 volts. I would like to install 6 volt red LED bulbs in the tail lights for better visibility. When I need to buy a flasher unit for this set up, which one should I purchase? I have been told that a Novita EL13 12 volt unit will work. I was also told that I can only use a 6 volt flasher unit like a Novita LL535. Has anyone gone down this road? Thanks.

Hi Bob
Just as far as the LED (my car is 12V) I had to try a couple of normal parts store flashers because those bulbs don't draw enough to actually flash.

Dean is right. For reliable operation with LEDs you should use an electronic flasher, not a thermal one like the Novita. One like this should do the trick. LASHER-R...

Thanks for the information. Will be checking out an electronic flasher instead of a thermal one.

We have LED lights in the rear of or '50 and incandescent in the front parking/turn lamps. We still run the the 6v thermal flasher with no issues.

The front bulbs seem to draw more than enough current to trigger the flasher at a normal rate.

You should always use the flasher rated for the voltage of your bulbs or LED's. I put Led tail lights in my 54 and all was ok until I put LED's in the front parking lights. Then the Current draw was not enough to trip the flasher. By adding a parallel resistor to the turn signal side of each of the front lights, this problem was solved. The LED's I used in front are two colors,white for running/parking and amber for turn signals.

My 1950 fleetline is currently 6 volts, and I recently converted the bulbs to LEDs. I'm currently using a CEC EF33W electronic flasher that I bought from

For bulbs, I purchased from My front parking light/turn signal housings have amber glass in them, so I used 1157-W19-6V: Cool White 100 Degree 6VDC bulbs in the front. In the rear, I used 1157-R19-6V: Red 15 Degree 6VDC.

It has worked very well for me, and the LEDs are plenty bright.

Upon your recommendation, I ordered 1 12v 1157 cool white 18 degree brake/turn signal bulbs from SBL. I tried another kind(amazon)and there was almost zero difference between brake and tail lights. They were returned. Hopefully, these will be better. I'm much more concerned about them being seem during the day.
