Can the reverse socket take a load of 20 amps surge? If so, I have 2 3000k h11 bulbs and ballasts laying around.

Unscrew 2 bulbs,you still have 40watts,but the area around you appears dimmer,except when you look directly at the remaining 2 bulbs,you still have 40 watts.

An incandescent fixture with four 40W bulbs installed will consume 160W of power. It will emit approximately 1960 lumens, as each 40W bulb will emit about 490 lumens (data for a 40W "soft white" bulb). Yes, unscrewing 2 bulbs will make the area appear dimmer, but this is because you will be consuming only 80W of electricity and outputting 980 lumens.

Lumens {simple terms}is the measure of light generated,per watt .

Lumens is the measure of the perceived power of light. Luminous efficacy is the measure of lumens generated per watt consumed. A 40W "soft white" incandescent bulb emits 40 lumens of light, and has a luminous efficacy of 12.25 lumens per watt (490/40). A typical 40W fluorescent tube emits about 2150 lumens, giving it a luminous efficacy of 53.75 lumens per watt.

It details a ''HOW TO'' re-wire your LED tails so that the "BRAKE LIGHT" section ALSO functions as the "TURN SIGNAL" function.. So the brake light section will light up when the brakes are applied & EITHER side will flash when the turn-sigs are applied.. ALL in the same SECTION of the light assembly....

You know what that does??
That frees-up the TURN SIGNAL SCETION to do what ever you like...

In this case... HE swapped out the amber incandecents for WHITE bulbs in the TURN SIGAL 'section'...THEN wired the old 'tun-sig section' to his REVERSE lights....

NOW in this case this was an xB1.... & he now has 4 reverse light bulbs burning when he puts it into reverse.. (check out the videos!!!)......
in OUR case,(provided that you have aftermarkert or SCION LED TAILS)
You would end up with 3 reverse lights....
1) your existing single in the bumper &
2) & 3), your new reverse lights where your turn signal once were...
WHILE still maintaing your turn-signals, only re-located......

Pretty freegin Slick...........
