So I took my dashboard apart this weekend to inspect the existing lights and work out what sizes they are, ready for purchasing LEDs and here's a few photos and links for anyone else doing this:
1. Remove the dashboard and dials
Two good videos on doing this
here and
here - I left my hazard light wiring connected and just rotated the unit to get the dash dials out - you need a Torque 20 screw driver - just in case you have to replay the video a few times to decipher that bit!
2. To get to the inner light bulbs
You have to separate the back from the middle and front of the dial unit - which seems impossible until you stumble across the diagram below like I did
Basically you unplug the connectors inside the unit, by using a screw driver from
outside the unit and then the back lifts off
3. Light bulbs
Once apart you can see there are 3 different types of bulb
Lower lights (seat belt etc.) = Black = Osram 12V 1.2w
Outside lights and most inner (behind LCDs etc.) = Yellow = Osram 12V 1.5w
Inner lights (dial illumination) = Green = OS 12V w3w E1 2GM w7k
The green ones are basically w3w bulbs in a holder, so you can pull them out and replace them with any w3w bulb or LED bulbs if you can find them - Halfords didn't have any LED ones so I bought normal ones temporarily = 504w3w
The 1.2w and 1.5w ones are a hard wired unit, with the bulb connecting directly to the little 'legs' that connect to the dash motherboard contacts
Interestingly Halford had these ones - 509T - which are direct replacements for the black 1.2w ones and work just fine - you can also use them for the yellow 1.5w they just won't be quite as bright
Dashboard now all bright again and off to find LED replacements for the above!
