After one of my console lights died, I decided to upgrade them to LED as they weren't very bright anyway. I looked for a led sbc bulb but couldn't find anything suitable. I decided to buy some LEDs and upgrade the existing bulbs.
For those that are new to electronics,
Connecting an LED across will make it glow very bright for a very short time and it wont ever do it again. It'll be buggered.
To prevent this it needs a series resistor. To spare you the Ohm's law calculations, a 470 ohm resistor will limit the current to an acceptable 20mA or so.
I decided to use 10mm high bright LEDs, available in red, green, blue and yellow. I bought these from eBay for about a quid each.
Using the photos as a guide, it's a simple matter to break the existing glass bulb, leaving the end cap.
Cut the long leg of the LED to about 4mm.
Solder the resistor to it.
Feed the resistor leg through the hole in the bulb cap.
solder the resistor leg to the end contact and the other LED leg to the side of the bulb.
After refitting the LEDs onto the bike, It makes a big difference, especially in daylight.
