Maybe not the correct place for this info, but here are the sidelights that have lasted a year so far...have them on about 40 mins a day.
They do aim up a bit due to the Saxo socket setting, but crouching to see what oncoming cars/pedestrians see, they work quite well in dim daylight and dusk.
They are about twice brighter than originals, using 4 watts, and are 12mm x 35mm.
DON'T expect super almost dazzling brightness like new cars have, they are nowhere near that...just a gentle upgrade that is a little more noticeable.

OK, so from China, but seem fairly good!
I have sampled a number of these Chinese cheapies and anything less than this bulb is not worth swapping. Seems its 4+ watts if you want a little brighter!
