LED Tail lights and Load Resistors
Here's me hoping Gearbox chimes in.. lol.. except that his cruise control works fine without one on his brake lights... 
Alright. So as most of us know, we need load resistors to use LED bulbs for turn signals and brake lights so **** works correctly.
However, is it necessary to use a separate load resistor for each turn signal and brake light, making us use 2 load resistors per tail light? Or will this wiring schematic I drew up work? I don't see why it wouldn't.

And yes, a 10W 10Ω wirewound resistor from radio shack (part number 271-0132) will work as a load resistor. I'm using those for my front turn signals. Got that idea from an xB forum. It costs $2 a pair instead of $5 per load resistor from say, superbrightleds.com. You just have to figure out how to mount them somewhere yourself, and double sided 3M tape won't work because these little ***** get pretty hot.

Re: LED Tail lights and Load Resistors
load resistor is a bad idea because you negate all the power saving benefit from actually having leds instead of filament bulbs. the turn signal hyperflash is super easy to fix the proper way. go get a tridon EP34 or equivalent electronic/LED flasher relay from auto store and swap it out for the oem one in the under-dash fusebox. i have rear filament signals, but full led front and side signals and i have the normal blink speed. if i end up putting back those depo led tails, i will prolly throw in a rear led signal assembly too without worry.
as for the led brake lights and cruise, diemaster already came up with a great idea for that as well. very simple resistor for the cruise module will fix it. and if you have the oem filament bulb in the 3rd brake assembly, there should be no problem. the fix is really only for those with a led spoiler or the 8thgen led lamp assembly swap AND led tails.

Re: LED Tail lights and Load Resistors
no problem lol. if you need info on where the stock flasher is, look up the diy for hyperflasher mod in the diy forum. but its pretty easy to spot in the fuse box. just a pain to slide that thing out after removing the screw.

Re: LED Tail lights and Load Resistors
Just giving everyone a heads up with interests in LED turn signals and replacing the flasher relay, the Tridon EP34 equivalent Blazer EF34 (packaging says FL34) doesn't fit into the slot for the OEM flasher unit. The tridon unit, I think, is a bit smaller than the OEM unit, but fits into the stock location just fine.

Re: LED Tail lights and Load Resistors
hmm and the blazer says "fixed load" so i doubt it wouldve worked. you want LED or "no load" flasher so it doesnt hyperflash with led bulbs hooked up. go with tridon

Re: LED Tail lights and Load Resistors
good to know.. It doesn't fit anyways, so it worked out in the end 
Just gotta get my 10 bucks back from autozone

Re: LED Tail lights and Load Resistors
this thread is relevent to my interest, xriceboyx im in the process of gathering info on leds on my turn signals (amber) from what i read here it seems like all i would need are the led bulbs, and tridon ep34 flasher relay to have it blink correctly?

Re: LED Tail lights and Load Resistors
That's the setup I'm running right now. I did the load resistor thing in the fronts at first, then the connection on the passenger side magically severed, so I went and bought the actual Triton EP34 flasher relay. Make sure you don't get the blazer one posted on post #6.
The only exterior lights I have right now that aren't LED or HID is my 3rd brake light, and I plan on putting an 8th gen EX LED third brake light when I get bored enough.
pics here (except my turn signals and reverse lights.. Turn signals are the same bulb as my brake lights, and my reverse lights are the same as my parking lights): https://www.civicforums.com/forums/p...9-post911.html

Re: LED Tail lights and Load Resistors
i see, well that seems pretty simple and its just a direct fit for the turn signals? i plan on having led in the amber turn signals, and hid for the foglights as of now and further down get some hid for the headlights, got any pics of your LED turn signals?

Re: LED Tail lights and Load Resistors
i used 48 led amber genesis clusters in mine, i think riceboy has a pnp bulb. the tridon ep34 flasher works great with em. i think its around 5w per side.

Re: LED Tail lights and Load Resistors
yep, I have pnp bulbs
and holy crap gearbox, that's a lot of LEDs.. lol

Re: LED Tail lights and Load Resistors
its not as bright as i wouldve wanted, mainly due to the tyc plastic cover piece. at night its great but during the day hard to see.
Re: LED Tail lights and Load Resistors
that looks nice gearbox, seems like it fits just about perfect in there, i like it, where did you buy those gearbox i searched but was not sure what bulb size and what not, also riceboy if u got pics of your set up in the headlights turnsignal , i wana compare the two

Re: LED Tail lights and Load Resistors
yeah its the customdynamics.com genesis cluster with 5mm leds. really sharp without any covering on em. the tyc diffuser kills the intensity. heres an old comparo to the stock tyc filament bulb, which ofcourse is the brightest bulb ever made so its not really a fair test. alot of other car with lower watt bulb and different reflector prolly wouldnt be as good.
parking light comparo (i disconnected the park light function tho later). led is brighter (right).

turn signal, bulb is brighter. this is 500 lumen 3457 amber bulb. (bulb on left, led on right)

led parking on the floor

led turn on the floor

the led park light on top is just a maxxima truck light module with 3 amber SMT leds

when i had dual park lights testing....but it was too much amber so now just the top is park and bottom is signal.

Re: LED Tail lights and Load Resistors
I have a video of my front turn signals on youtube

and there are some pictures of them in this thread:

Re: LED Tail lights and Load Resistors
it's kinda hard to get a good picture of how bright my turn signals are because when the parking/headlights are on, they're white, but once I turn the turn signal or hazard on, they flash amber. Bulbs were expensive as ****, but I had a mishap with the first set of bulbs that I ordered, so they sent me a new set and refunded half the cost.
Re: LED Tail lights and Load Resistors
wow looks nice gearbox, im diggin it, that last picture looks like its got alot of amber, looks great nontheless, but over where im located (la) i think that would be a problem due to so much light exposure, im liking the idea of the parking lights might just do that instead although im on OEM headlights and i plan on keeping those, would that be a problem as far as fitment? from the pics looks like you both have the angel eye headlights

Re: LED Tail lights and Load Resistors
we have the same headlights (TYC projectors), but I custom-fitted mine with CCFL angel eyes by way of double stick tape. These particular ones don't come with angel eyes on 'em.
Re: LED Tail lights and Load Resistors
oh alright i see, i like both of your led lights, im aiming at the parking lights (only amber peace light) but again, is there any fitment problem to have them on my OEM headlights?

Re: LED Tail lights and Load Resistors
They use the same bulbs (turn and parking) as a stock headlight. Only difference is the TYCs split the hi/lo beams from a dual-filament H4 bulbs to 2 separate single-filament H1 bulbs.

Re: LED Tail lights and Load Resistors
leds in the oem light are tricky, not as much room or round areas for mounting. but i bet you could fit the led park light module in that small peanut reflector. the oem light uses a 7443 i believe for 01-03 light. tyc has 3457 signal bulb. parking lights are the same.

Re: LED Tail lights and Load Resistors
yea the turn signal led looks pretty big for the hole on the oem headlight from the pics, in those pics is that the top led park light, can you forward me to where i can get some of those

Re: LED Tail lights and Load Resistors

Specifically, the WLED-WHP5 bulb.
Those are the bulbs I used, but for some reason, 4 of the 5 LEDs on my driver side seemed to burn out, so I removed them and took the bulbs that I had from the mishap I mentioned earlier, removed 10 of the LEDs (PLCC-2 type SMD LEDs), and soldered them in place. I still have the same bulbs in my reverse light sockets, though. I tested the LEDs individually after I removed them and all of them still work fine
I more or less converted the bulbs to these kind, minus one LED on the top.

Re: LED Tail lights and Load Resistors
On a different note, but still related, I just nabbed an 8thgen LED 3rd brake light off ebay for 30 bucks shipped. WOO! lol
Re: LED Tail lights and Load Resistors
from the brief info related to those led lights im not so sure if they would fit the oem headlight, your running the bulbs with the tridon ep34 and that is all? gearbox where did you pick up yours from, from your pics that park light seems like what im aiming for
