FAQ - Dash Switch Illumination

A simple guide to changing the LED's of the dash switches.

you will need solder, soldering iron, possibly a pair of scissors and patience.
2.5v 3mm LED's in any colour you prefer.

- Remove all the dash switches including the headlight switch. remembering where each one go's.
- on the push switches pull the bulb holder from the back of the switch.
- pull the LED by the bulb and completely remove it noting the resistor on the bottom of the holder.
- with your new LED insert the legs into the guides. the longer of the LED legs go's with the resistor. THIS IS ESSENTIAL FOR THEM NOT TO BLOW.
- re-insert the holder into the switch. there should only be one way it will fit back in, but if not the resistor go's at the bottom.
- repeat for all push type switches and fit them back in the dash.

- with the headlight switch you will either need to de-solder or cut the existing LED out.
- you will also need to cut your new LED down to size but also make a note of which is the longer leg.
- the longer leg of the LED needs to be soldered to left contact(working from the behind the switch).
- finally solder the other leg and push the LED into the same position as the original.
BE CAREFUL NOT TO MELT THE PLASTIC OF THE SWITCH WHEN SOLDERING!
- re-fit into the dash and test.

the best LED's to use are diffuse ones as this lights the entire icon and doesnt concentrate the colour on one point.

Re: FAQ - Dash Switch Illumination

as requested i have added some images which help with some of the desriptions.
1)orientation of the bulb holder in relation to the switch.
2)position of resistor on the bulb holder
3)long leg of LED paired with resistor

4)view from behind the headlight switch
5)bend the old LED to cut out/insert the new LED in the same position. it can be bent into position once soldered.
6) solder the contact points remembering that the long leg(after its been cut) gos to the left contact.

Re: FAQ - Dash Switch Illumination

Just adding to this, anyone farting around with LEDs in their cars.
Do not put an LED in as your battery or ECU/injector light. Just..don't ok - trust me!

Re: FAQ - Dash Switch Illumination

well certain systems require the correct resistence over the circuit.eg the charging system requires the correct rated bulb in the circuit.
as arc found out an led doesnt do this so leads to a poor charge on the battery

Re: FAQ - Dash Switch Illumination

I changed all of the bulbs in my dash to LEDs - window switches, clock, heater controls, speedo etc. Have a look at the video to see the colour-changing ones in the switches - the window switches weren't done but now they are blue. I make no apologies for the soundtrack...
