Number plate/interior lamps (white):

These are single sided - the LEDs are mounted only on one side of the pcb and shine sideways relative to the lamp axis. This is just what's required for the number plate and interior boot lights. Because LED lamps only work when a forward current is applied, the risk was that they would only work when pointed away form the number plate! However, we're lucky; they illuminate the number plate very clearly and are a huge improvement over the original wedge-base lamps. They've been in for about a month now and have given no problems. Because they shine sideways, I don't think they'd be much good for the front side lights. Recommended, but see the comment at the end of this post*
Brake lamps:

These are very bright. They just (and only
just) fit through the hole in the back of the Multipla lamp cluster. Not particularly well made, but do the job. Because the lens for the brake light part of the Multipla lamp cluster is patterned/frosted with a strange 'bubble' pattern, the lit surface of the lens is evenly illuminated and quite a bit brighter than a standard 21W single filament lamp. No load resistor built in, but as the Multi doesn't run CANBUS, this isn't a problem. Recommended, but see the comment at the end of this post*. Because the lamp contacts are coaxial (single centre contact on base of lamp + metal outer casing) they aren't affected by incorrect current direction. Hopefully these will be fit & forget.
Indicator lamps:

Just like the above brake light lamps, but orange. Two points to note:
1. As mentioned in the above posts, you'll either need to fit load resistors to make them flash at the correct (1Hz) rate when using a conventional indicator relay, or fit an electronic relay.
2. Because the Multipla lamp cluster lens for the indicators is clear and not frosted, the lamp is clearly visible from the back of the car. These LED lamps are quite directional, so the light spread across the lens (and reflector) isn't great. Qualified recommendation, but see the comment at the end of this post*
Indicator relay:

Does the job and is a direct replacement for the original relay. Restores correct flash rate without the need for load resistors. Slightly odd synthetic indicator 'click' noise. Delivery took a while for this item.
* - None of these lamps appear to carry an 'E' mark so strictly speaking aren't legal for road use. That said, it would take an eagle-eyed pedant of an MOT examiner to pull you up on this point, except perhaps in the case of the rear indicators, because the lamps are clearly visible through the cluster lens. With ever more stringent pass criteria for MOTs, I think this may be something added to their (DfT) hitlist in future, especially as LED lamps gain in popularity.
