[W124] Brake fluid

[Frank Smyth]

Hi folks

What brake fluid are you guys using ? The owner's manual and the Haynes
manual for my '92 fail to mention which flavour the car likes. I assume
DOT4 or DOT5.1 would be okay ?

Also, from where can one buy the little plastic bulbs that light up the
heater control-knobs ? Am unable to buy them in the usual places
(haven't asked Mercedes-Benz yet though)

Cheers
