I installed these last year and it was a big upgrade in terms of brightness over the factory bulbs.

Just installed the reverse lights with some Phillips 921 Led, they look awesome!! Also, replaced the dome lights on all the doors to match the led.

Default Warranty

Will replacing the backlight on a 19 450H void the warranty?

Also need a fool proof instruction on how to install for a noob if possible

No and there’s no instruction needed. On the inside of the tailgate there’s two square pieces pry them out without breaking them. Pry a little at a time on all sides until you figure out which is the side your supposed to pull. Reach in twist the bulb socket, pull out the entire bulb. Pull it out of the socket, push in the new led bulb. If you use cheap bulbs they might be directional, so once you have them both in have someone press on the brake pedal and put her in reverse. If they both light up your good if not turn the bulb as the polarity is off. Better bulbs now aren’t polarity sensitive and work both ways. Once your all good twist the sockets back into place and replace the carpeted cover carefully. Close the trunk and test that the lights are both still working. Now stand back and admire your new cool white lights.

Not necessarily a better/worse bulb situation. Depending on the polarity solution used, there can be electrical efficiency, heat, and reliability concerns in trying to make a compact bulb (such as a 168 wedge) non-polar. Large lighting brands (such as Philips) felt this to be a worthwhile compromise as their products are being sold to the average consumer who may/may not be cognizant of electrical polarity in this context.

I was just wondering bc mine does not have the triple beam LED headlights and I thought only the ones with triple beams come with full LED's all around.
Does your have the triple beam LED headlights?

Today I replaced all turn signals, reverse lights and cargo lights with the LED bulbs:
Front turn signals - 7443-AHP28-T-2PK: Amber x2
Rear turn signals - 7440-AHP28-T-2PK: Amber x2
Reverse lights - 921-WHP10-TL: Cool White x2
Cargo lights(you need 3 of them bc there is 1 in the hatch itself) - 194-WHP6: Cool White x2 but need 3
Got them from superbrightLED and I bought the brightest ones







Here are some pics and videos

Red face worked for me!

I ordered and installed the reverse and turn signal LEDs using bibika027's links. They are much brighter! The installation of the rear turn signals is a little tricky. I used the directions from the RX manual (page 620) and created no scratches nor broken tabs.
