Dashboard Light Parts Numbers

[Rusty]

What bulbs do I need for the dash?

I see there are white (2W?), black (1.2W?), orange, blue and jade green (1.0W?) lights in holders. What am I searching for to buy replacements?

Might be worth adding in the numbers for the heater control bulbs too...

I also want to know these, ive got a couple of the orange ones that are out on my dash binnacle.

The only one i know for sure it has to be "at least 2W" is the battery light.
Iff is lower wattage the charging system will not work right.
All the best!

I think mine was 1W

The only one i know for sure it has to be "at least 2W" is the battery light. If is lower wattage the charging system will not work right.

Huh?

That makes no sense.

Don't know what the S2s came with but the UrS4s came with 1.1 W orange base bulbs. The common upgrade is to light green base 2.0 W bulbs. OSRAM is a typical supplier.

Iff the bulb has lower wattage, the field current needed for the regulator is to low...lower than aprox 3 volt as the resistance in the bulb is higher. you need more voltage at startup for the regulator to start control the field current in the alternator.
The field voltage comes through this bulb....

Forgot to ask, "What, you can't see paradise by the dashboard lights?"
