Headlamp pilot light x 2, side indicator x 2, number plate light x 2, roof front map reading light x 2, roof rear courtesy light x 2.
Be careful with the roof rear courtesy lights, the holders are not designed to work with LED type bulbs, they short circuit very easily due to the shape of the bulb retaining/contact clips.
Quick fix, long nosed pliers, bend the side of the clip outwards so it can not contact the other side of the bulb.
Not so quick fix, for those who have the time and passion. The old glass bulbs had a single wire at each side of the bulb so were not affected. The LEDs have a broad flat contact area that reaches right to the side edge of the bulb, it is this which arcs on to the L shaped holder contacts. With a small (Warding/nail File) file, put a 45 degree chamfer on the side of the bulb contact area. Only has to be 1/2 mm deep. This will separate the arcing points, and retain the keeper value of the holder's L shaped contact clips.
Pretty much all these bulbs are the same 'Chinese' quality fitment. It's the design of the interior roof bulb holders that are not totally suited to these LED bulbs. Not a problem with standard glass bulbs.
I like the LEDs. My interior lighting is now LED, the cabin is half 1/2 white for everyday/night use, and at the flick of two switches can be 1/2 red front and back for dogging or skinning up! Simples...
The LEDs that I have in my interior are similar to the old glass bulb, wire either side, so don't short, they aren't the printed board type holders, work a treat, should be a link in my thread in my Sig, first page with pics.
Had a look at your thread BigDov. They look like the business, no chance of arcing at the edges.
For front centre roof light there is room for a double row SMD festoon.
Interesting to see they are not canbus friendly bulbs.
Concerned to see that the 501s in the ebay add. have both wires on the same side, this will not work in rear roof, need to be one wire each side.
