100w 8 ohm load resistor fix hyperflash?
 

I wanted to run this by someone more knowledgable than I. I ran LED turn signal bulbs in my Acura front and back with one 100w 8 ohm non-inductive load resistor on each side. This should also work for the fit correct? I know people use two 50w 6 ohm resistors. Can I get away with one?

You need a resistor that approximates the impedance of the original light bulb, connected in parallel across the LED. (Well, it really should be a bit higher impedance so the parallel combination is equivalent to the original bulb.)

Typical turn signal bulbs are around 25W at 12.8V or so, which means they'd have a resistance of around 6.5Ω or so. An 8Ω resistor may work out fine particularly if you're replacing only the front or the back turn signals with LEDs; if doing both, I suspect you'd still have high speed flashing with it. (The 100W power rating is very much overkill, but that's not a problem. You'd have to have the vehicle electrical system operating at around 28V for this resistor to dissipate 100W.)

I'm not positive that the front and back turn signals are on the same circuit on the Fit, though I suspect that's the case; it would be a quite unusual and strange wiring setup if they weren't.

i have a triton v3 switchback and did not use the included resistor for them and no hyperflashing. try without the resistor first before u go make one.

Thanks for your reply. I still don't understand the whole ohm thing. I used this same resistor in my Acura which had the exact same bulbs and ran LED's both front and back with no hyper flashing. The reason I like it it because it is massive and dissipates the heat really well. I would also rather stick it in the rear as I can hide it better/ keep it out of the weather.

I tested them and they do hyperflash. I might take a look at the Tritons, where did you get them? The switchbacks I found are 4100k which I like better.

they are pricey.

A 6 ohm 50 watt resistor should work better. 100 watt 8 ohm is simply too big overkill. I use the ones below with Type A switchbacks in the front and two red LEDs for the back. Love them!

I know the resister has to be wired up in parallel with the bulb -- for the front DRL / turn signal, do you know which wire is the power for the flashing turn signal?

Nevermind -- it's the middle one.
