How many dash bulbs do I need?
 

I am pulling the dash cluster to repair the odometer on my 85 300 TDT and while I'm in there I want to replace all the bulbs. Fastlane has the push in bulbs and the bulbs with the black base but I don't know how many of each I need.

Thanks,
Chris

I am about 90% sure it needs 2. I am sure someone will chime in if I am wrong

For just the cluster its two. The other part of the dash for the klima and switches needs like 5 or 6 of the little teeny bulbs. (1.2 watt)

An '82 300D has eleven lamps in the cluster itself. Your model is probably pretty close to that.

??? Where are there 11 lamps? I count 4 for the klima....1 for the fiber optic spider....2 for the instrument cluster....and one for the shifter. Thats only 7? where are the other 4?

I'm going to take a guess. Just the ones that are burned out.:D

Cluster illumination: 2
Turn signals: 2
Brakes: 2
Seat belt: 1
Pre-glow: 1
Battery: 1
Low fuel: 1
Hi beam: 1

Two for illumination, nine for indicators.

That's a great strategy for someone who enjoys removing his instrument cluster. Folks who are not included in that population would do well to replace all the lamps while the cluster is out. I suspect that the OP has that in mind.

Hence the grin face. I would do all of them in the cluster when I had it out. Then all of them in the Klima the next time I had that out.

Sorry, I should have specified - I'm pulling just the instrument cluster. So the bulbs for the instrument cluster are the bigger ones with the black base or the little tiny ones?

This may be my first bonehead question but...what is klima

Just call Phil, I bet you he will get you the right ones.

Klima, climate control unit, CCU. I'm sure it has some other names too.

OK, I've caused enough confusion for one day, I'm going to work now.:)

Klima is the climate control panel. If you only want to replace the two gauge face illumination bulbs, you can do it without disconnecting the cluster. You need to take it out completely to get to the other bulbs. The larger ones are #2821 and the smaller bulbs are #2721. Consider using LEDs since even the correct wattage stock bulbs can melt the plastic they are housed in.

LED's
 

Has anyone done LED's in their cluster? Where can you get them?

Check out this thread. I posted links to all the bulbs that will fit your car with no modification. You can replace all the 2721 bulbs with a 74 Wedge Base LED. I plan to put those in soon myself.:)
