Dash warning lights

Hi all
My diff lock warning lamp and main beam warning lamp have blown in my 90. It’s an early one with the sort on papery circuit board, and I just wanted to confirm that the part number for replacements is AMR 3339.
IIRC the bulb holders are little plastic things that fit with a quarter turn......
Cheers

Are you sure they have blown, the board gets a bit corroded give them a look first.
