I'm assuming the LEDs are on the LHS, since these seem brighter, in which case, they certainly appear to be quite an improvement. Do you also have parking sensors on the rear bumper?

Both stop and tail have the same output so I will see if I can turn the stop lamp brightness up...

Yes, reversing sensors , along with many other.... " improvements "

:-? ??
I'm confused by this statement. You've found some that are adjustable??
I've had a problem with poor definition between Stop & Tail, see my earlier posts back on Pages 2 & 3.

This video was my 1st attempt with lamps that had poor definition between the two inputs:

Subsequently I fitted these to good effect.

Can't adjust the power level as such , but replace the LED array with a larger one...

P.S. Your stop/tail led lamp,have you tried putting power to one of the connectors and measuring the " output " on the other connector....I say this as I had a problem years ago where the difference in brightness was achieved by effectively shorting out a dropper resistor within the lamp....worked fine BUT provided power from the accessories position to the ignition position ( or vice-versa ) when the brakes were operated and caused me plenty of head-scratching..

Unable to edit the above post but I do like the way the brake and tail lights are seperate but within the same unit..

Ordered LEDs arrived and tested , there is no "bleed" between the stop/tail contacts , that's good , the only other noticable thing is that if the brake" light" is on , there is no further brightness when operating the sidelight , but no problem there....All is good

Well there wouldn't really be any noticeable increase with a regular lamp either, seeing as you'd be adding just 5w to a 21w brake lamp.

Yes, I suppose 26w is not much brighter than 21W....
