Load Balancer for LED Front Turn Signals

So I picked up some 50w 6ohm Load Balancers for my front led turn signals. They are the plug and play ones since I didn’t want to do the universal one that I would have to splice into the OEM wire harness. I just went to install them and boom I get one flash when I turn the turn signal on and that’s it no response afterwards not even an indicator on my dash. I don’t know what’s going on any clue guys?

 

Too much load on the circuit is my first guess.

 

Do the headlights go back to normal behavior with the resistors removed and halogen bulbs put back in?

 

Yup

 

Yeah, I think it's overloading the circuit. I have done a fair amount of experimenting with the turn signals on the SR's, and anytime I get that, I use a smaller resistor.

 

Damn I’m so over trying to get these led turn signals to work. I only thing I haven’t tried is just using one resistor on one headlight and use the other led bulb plug straight into the OEM wire harness.

 

25w 6ohm are what I use

 

A smaller resistor will increase current. As in more load.

 

Those in the picture are 50W it looks like. Did you try just the LEDs? Maybe they already have resistors built in?

 

Yeah, I was referring more to the Wattage as opposed to Ohms

 

Yeah the LED bulbs I bought have built in resistors I believe. They are GTR Lighting Carbide 2.0 series. But if I plug them straight into the OEM wire harness they hyperflash

 

Are the resistors just on the turn signals?

 

Yup just on the turn signals. I also have led low beams and led fog lights too so idk if there is too much load.

 

You need to find a sweet spot. I ended up using these with the SR's when I was converting them to the OEM LED headlights: PARKING LIGHT ERROR FIX VLR-25 + DUOTAP HARNESS (vleds.com) they are 6W. Are your headlights anything funky? Or just trying to convert the turn signals to LED?

 

That load won't affect it. The turn signals on these are just a pain to find that right spot with.

 

Yeah I’m just trying to do the front turn signals. I really hate how the the truck has LED low beams and fog lights but not led turn signals. It’s so off putting.

 

The watts is only an estimate of how much power can be put through it before melting. Lowering the watts alone, does not change the current allowed to pass through it. Merely affects how soon it catches fire.

Put orig lights back in, turn them on, put clamp meter on wire and measure amps being used. Then put in leds in and do the same. Then find right ohm resistor to reduce or increase amps to match original light amps.

 

No, on these resistors, Wattage is load (as in a function of load. So a 6W resistor adds 0.5A load) So the 50W resistors will add 4.2A at 12V.

 

Remember, for automotive resistors like this, the load is parallel, not series. So the only wattage going through them is based on the resistor alone. You can put a 6W resistor on a 10A light bulb. As long as it's parallel, it wont be affected by the 120W (or 144W whatever, depending on voltage). You just have to make sure the circuit as a whole (wire and fuse) can handle 150W.

 

But, just incase it wasn't confusing enough, yes, the 50W stamped on these is a melting point if they are 6Ohm. So, you are right, they are 25W effective added load.
