Title: K75 replacement LED dash lighting - bulb size/number?
Post by: k75novice on April 06, 2018, 10:59:57 AM: My backlighting on my dashboard is dying; all but one bulb has gone out. I have found this website that purports to sell an LED upgrade kit, but I've sent 2 emails and heard no reply after over a month: http://www.kbikeparts.com/ledupgrade.htm

Does anyone know the size of the OEM dash bulbs so I can find a suitable replacement on my own? Any lettering on the OEM bulbs is illegible, and the replacement bulb I ordered via the part number is not green tinted like the ones I found in my dash, and isn't labeled with size/wattage.

Go here (https://shop.maxbmw.com/fiche/DiagramsMain.aspx?vid=51739&rnd=07242017). Click on Instruments Dash then click on the Single Components diagram. You'll get a parts list with descriptions.

Word of warning to anyone else trying to replace bulbs- the green OEM bulbs are NLA, as indicated on Max's site, and when I tried to order some from Max a while back, they sent me the "superseded by" part, the non-tinted bulbs.

I have used the green, red and blue colors in my bikes, and they work great.

Many years ago I owned a '62 GT Hawk (Studebaker) which had red dash lights. I could have sworn they were coated with nail polish ...
