At the rear, I've replaced the brake lights and cobra with LEDs and the difference in light output is significant. Reflected against the garage door, I would say triple the output of the standard bulbs. These LEDs are white. I prefer red light covers.
From a safety point of view, this is a cheap and simple upgrade.
Agree and I think the LED brake/tail lights are a simple and probably essential upgrade. I get my LED bulbs from Duncan who also advises Red LEDS
