Title: LED Bulb Conversion Parts
Post by: ERNurseScott on February 02, 2013, 06:01:34 AM
Hello everyone!
I am wanting to switch out my stock rear parking lights/brake lights and turns signals and the front parking/turn signals with LED's. I have heard great things about VLED's but I am completely confused about if I need resistors or not if both the front and rear lights are being replaced. Can anyone who has done this mod help me out? What exactly do I need to buy? For someone that is not electrically inclined (at least not with vehicles), is this a relatively simple mod to do? The interior LED conversion seems easy...simply switching out the OME bulbs with the LED equivalent...but the external one confuses me with needing or not needing resistors, etc.
Any help will be much appreciated!!!

This might help

Borrowed from TNX

During my addiction I have been getting a lot of questions about my setup; which size lights are the stocks, what size LEDs do I need, where to get them, etc. Thought I would make an all-inclusive type deal for all such queries. Next to the specs is the link to the V-LEDS online store w/ examples, prices, etc. So, here goes...

Front running/turn signals
3457 (amber, and are interchangeable w/ 3157) ( ( ( (

Rear turn signals
3156 (red) ( ( ( (

Tail lights
3157 (red) ( ( ( (

License plate
168 (white) ( ( (

Reverse lights
921 (white) ( ( (

Front sidemarkers
194 (amber) ( ( (

Dome/map lights
DE3175/3175 (several color choices) (
White - ( or (
Red - (
Blue - ( (

Load resistors
These are needed to stop the rapid-click turn signal from installing the turn signal LED bulbs. ( ( (

These are specs for my 2005 but I am 99.99% sure they are the same for all models '05+. You use the same size/classification as the stock lights as you do for the LEDs! For example, the reverse light bulb is 921 and requires a 921 LED bulb - too easy.

---How To Install Interior LED Dome Lights---

Front map lights, HID white 9-LED bulbs from V-LEDS ( (

The housing simply pops out, like so.

Next, unplug the wiring harness.

Then you will need to remove the outer plastic casing by popping off the four gray tabs along the outside.

And also pop off the clear plastic clips holding the covers on.

This is not what the stock bulbs look like, these are the 12-LED strips from Cynicroute and his XterraMods site.

These are the 9-LED bulbs replacing the 12-LED strips.

Remove old bulbs and pop in new LEDs. Be sure to test fit by plugging wiring harness in after inserting new LEDs, they are polarity-specific and if they do not turn on then they simply need to be turned around!

Pop the clear plastic covers back on as well as the outer gray plastic housing.

And, voila! Let there be (LED) light!

---How to Install Rear Passenger & Cargo LED Dome Lights---

These LED's are the HID white 16-LED bulbs from V-LEDS ( (

Much like the front lights... Use a screwdriver or knife tip to pop off the plastic cover.

There are two screws to undo (phillips head).

Pop out housing and remove wiring harness.

Remove old bulb and insert new LED's.

Again, be sure to test them (re-plug the wiring harness in before re-assembling everything.) to make sure they do not need to be swapped around. BUT, if you test them and you see this, a very faint glow...

DO NOT WORRY! I thought I had duds (again) but once you screw everything back in it lights up as normal. The screws must act as a sort of grounding or something. It should look *bling* like this once it is all back together.

Reassemble the housing (plug the wiring harness in, screw the two screws back in, and pop the plastic housing on). Here is your finished result.

The same goes for the rear cargo dome, exact same directions for install as rear passenger dome.

---How to Install Resistors---

When swapping out your front AND rear turn signals for LED's, you will need to install a 3 ohm resistor. If only doing the fronts or only the rears, a 6 ohm resistor will do the trick. This will solve the blown fuses and rapid-blinking issues. Since there is more free space to get your hands on to the necessary wiring in the rear taillights, I recommend going this route. Very simple install - wire tap one end of the resistor to the black negative wire and tap the other end to the green positive wire. Should look like this...


---How to Install Front Side Marker LED Lights---

These are the 194 amber LED bulbs from V-LEDS, here: (

Pop open hood and go to light housing area, the bulb is very noticeable and accessible, seen here on the bottom right.

Twist counter-clockwise and pull out harness.

New LED bulb.

Old (L) vs. new (R).

Insert new LED bulb (same deal goes; if it doesn't light up then just pull out and re-insert the other way).

Re-insert new bulb/housing by twisting clockwise and, voila!

After a long time of blowing fuses and/or rapid clicker, I FINALLY realized my problem... or X's require a SACK Type front LED bulb. You can get it here, like I did - (

And adding this to my archive of stuff to put on my truck... ;D

No problem. I actually had it open when you posted because I was looking at it.

Great list, I have a lot of this stuff.  Its good people need to know the resistor info about their turn signals.  People put in the LEDs and then wonder why their blinkers go nuts.

So, in your opinion, what is a good balance between price and brightness? Some of these bulbs are $70/pair down to $15/pair.

good question.  I bought a lot of mine on ebay with a general bulb size search.  I have mixed feelings because I really like the 7w backup lights, but I ended up buying 2 pairs cause I broke one. (

Also, for the interior I used something like this, (

But we need to measure because i dont remember if all the dome lights are 31mm.  I found that the ones that come on a pc board that you are supposed to sticky tape somewhere dont work well, either they get bumped around or twisted and LEDs start going out.  So you want to get the right size to actually replace the bulb like the one I linked.  I have installed a lot of non oem replacement LEDs in my truck and I love it.  You cant really leave the lights in the X on, they turn off after an hour.  But when I camp I run these things all night and never have to worry about the battery dying.
