Don't know if zip ties the that load resistor to the wire is a good idea. If that load resistor heat up, it will melt the insulator and short out the electronic. Better use a good aluminum tape and tape the resistor to the metal part of the car.
Try to leave the flasher on for a minute or two (typical wait time for a turn) or longer (as if you leave the emergency light on) to see how hot it that load resistor get.

I did try leaving it on a few minutes and barely warm to the touch. I figure signalling through traffic it should be fine. I wanted to avoid vibration and rust by attaching it to the car. I'll take it off some time soon to double check on things

Awesome DIY post. Thanks! Did you replace your license plate bulbs as well with LEDs? Is so, any recommendations?

E46CT

Thanks! The license plate has LEDs stock

dj2020

Thanks for your DIY and links to the LEDs!

Curious, did you mount your LED panel on the outside of the plastic cover trunk light? That's what I ended up doing because I could not fit the LED panel behind the plastic covering.

E46CT

Oh I forgot about that part. I trimmed the interior of the plastic to force the panel to fit. Used a pair of snippers to snip away at a little of the plastic

Looks like I'll have to revisit that and trim.

Do you have a recommendation on LEDs that are brighter than the Yitamotor T10 Wedge but not has bright as the LED 15 SMD panels? The panels are just a tad too bright in the front and rear dome lights for my tastes.

E46CT

you can paint some of the leds black. i think they make some panels that have fewer leds. maybe a 7 SMD panel?

dj2020

Awww...never thought to black out the LED with paint or marker. I'll try that or maybe block out some of the LEDs with something translucent.

E46CT

Yup or just use electrical tape. Resistant to heat and its black itself.

Hmm did not work for me. I got the resistor at the tails like you. Today I try to put some led in the front- hyperflash agian.
Ok the led are cheap and no ultinons like at the tails.

E46CT

are you sure the resistor makes a clean connection using the supplied wire taps? The metal has to actually touch. You can have the false impression the resistor is not working if contact is not made. By definition it has to work.

Great write up. LED rear turn signals are just so extremely eye catching. There's just something about that crisp, sharp output that adds just enough oomph to the car.

Thanks for the thread!

you know they now have turn signal leds with everything built in... just plug and play. I have these in my car
