Installing exterior running/ turn signal LED's: Write up

What's up guys, a few weeks ago I finally got sick of staring at these 3/4" red and amber LED truck lights taking up space on my work bench so I decided to mount and install them.
My game plan for the rear was to mount 2, red lights on each of "out-dent's" on the bumper as running lights/ functioning brake lights, illuminating brighter whenever the brakes are applied.
As for the front I mounted and installed 2 clear (illuminating amber) LED's on each of the "out-dents" on the front bumper which would be running when my lights were on, as well as functioning turn signals and hazards.

Tools needed:
-a hole saw set, due to the fact that no drill bits are large enough make a clean hole large enough
-sand paper
-hobby knife
-16G speaker wire (pos and neg)
-soldering iron + solder
-electrical tape
- liquid gasket sealer
- and obviously, the LED lights

I did the rear end first so, we'll start there.
Step 1: remove the 4 10mm bolts to your tail lights, and pull it free from the body.
Step 2: Remove the rear plastic stripe which actually holds the bumper on, and remove the bumper.

Step 3: splice into the brake light wires, and test which is pos. and neg before installing.
Step 4: Cut the 2 hole's in each of the out-dent's in the bumper, next Grab your sand paper and sand the newly drilled holes a good bit so that you may fit the grommet into the bumper, next grab your hobby knife and cut off the excess plastic so it is flat..apply gasket sealer and then force the actual bulb into the bumper, making sure that it is aligned straight up vertically.
Step 5: Grab your wire strippers and strip part of each of pos. and neg. wires, place inside/ or wrap around the led light connectors, then solder each to ensure the connection will stay in place.

Step 6: reinstall your bumper and tuck your excess wiring under the styrofoam inner bumper, which you should also drill through to have your wiring in a safer location.
Step 7: pop back on your plastic "bumper holder" and test em out!

Now, moving onto the front bumper....almost identical process.
Step 1: pop your hood, remove your grill assembly, pop off the plastic pins holding the bumper on and remove the bumper.
Step 2: Drill the holes in the 2 out-dent's of the bumper, start sanding the inner holes your just cut a good bit...grab your hobby knife again and cut off the extra out-dented plastic that was left after drilling.
Step 3: press in the grommet from the LED into the bumper, then apply the gasket sealer and press the LED's into their new homes..remember to keep them both vertical so they don't look like s***.
Step 4: grab your wire strippers and cut off a half inch of the front outter turn signal, twist the new pos and neg wires to the stock turn signal wiring..solder, then of course wrap with electrical tape. Note: remember to cut holes through the styrofoam inner bumper again to run the wires through properly, then reinstall the bumper and check out your good work!

Also, for whatever the reason my LED wiring was black-positive and white negative....so whatever type you use, be sure to determine which is which otherwise you'll be pulling your hair out trying to figure out why they aren't working.

So to wrap it up, the tail lights are running whenever the lights are on and then when the brakes are engaged they illuminate MUCH brighter. The front's are also running whenever the lights are on and when the turn signal's are used they too also become much brighter..otherwise running, they're dimmer than I expected but all and all i'm pretty happy with them and have received multiple compliments from even non jeep owners! Hope I inspired someone to do this simple mod or something similar..cheers!

yeah a buddy of mine has rectangular secondary "reverse lights" on his xj but he hardwired to a switch so he could light up the trail for whoever was behind him.

If I were you i'd just get some good LED reverse lights off amazon...mine are stupid bright and I can actually see what i'm backing in to now lol
