Default 1968 Sequential flasher too fast.

Hello all,

I have been installing dynamite sticks on a '68 shelby clone but I am having problems getting the lights to signal slow enough to reach all three lights. I have the cobranda flasher installed but it's still not slow enough. I've heard of people pulling apart the orginal flasher can but im not sure what exactly it is they modify in them to make it signal slower. Any information would be helpful. Thank you!

Are they led lights? I hear that LEDs flash quicker than normal bc of some electrical mumbojumble. Worth a quick google.

Single LED's should flash slower if at all, with a regular flasher since the curent draw is so much less. If they are regular 1157 with a regular flasher, they would flash faster than normal. An LED flasher does not rely on cuurent draw for flash time. You may need a longer duration LED flasher or if 1157 bulbs, one that trips at a higher current load. Think trailer light flashers, if 1157's.

Venom - Are you using a mechanical flasher?

Smitten - I believe the opposite is true, where LED's would flash quicker because of the lower current draw.

I'm not familiar with dynamite sticks, but if they are LED's and you are utilizing a stock mechanical flasher, then the resolution is to switch to an LED flasher. I suppose you could install a resistor inline with the LED's if you had to utilize your existing COBRANDA flasher. Another option is that you could find a low current flasher for a different make/model (probably from a motorcycle).

Good luck.

I figured out what the problem was. the battery current was only pushing out 12v. For the system to sequential correctly on all three lights the car had to be running and producing 14v. I also ended up using a hazard flasher instead of the Branda one I ordered. Everything works perfect now. Thanks for the feedback though I should have made it clear they were bulbs and not LEDs.
