BMW glovebox torch modification

This article is a repost - I originally posted this modification on my blog. I don’t have the vehicle any more.

I modified my glovebox torch, adding a more powerful battery and converting the light source to three ultra-bright white LEDs.

At the moment this is just a proof-of-concept. The torch at the moment is controlled by a momentary switch (so you have to leave your finger on the switch for the light to stay on). I will either fit a standard rocker switch into the side, or build a flip-flop circuit so that the current switch causes the LEDs to latch on or off.

With three LEDs, the torch is very bright! It dumps all over the standard bulb. The three LEDs draw 20mA each, and I’ve fitted the torch with a 200mAh NiMH battery, so a fully charged torch should on paper last over 3 hours.
