Brighter Sidelight Bulbs

Hi. As the days are getting dark, on my regular car, I'm running with heads on all day, most days anyway.
On the 5, I would prefer to keep the lights down, as the car looks better. The sidelights on the MK1 are pretty dim though.
Has anyone upgraded with LED/brighter bulbs? I would like to be a bit more noticeable on dark days, and don't want to shell out for a sleepy-eye kit.
