521newbie Posted January 9, 2010 Report Share Posted January 9, 2010 Will using 158 bulbs in my instrument cluster work? I can't find the 157's that are printed on the bulbs for my 521. Quote Link to comment
datzenmike Posted January 9, 2010 Report Share Posted January 9, 2010 What are the wattage? Are they same or higher? Quote Link to comment
DanielC Posted January 9, 2010 Report Share Posted January 9, 2010 Bulb specifications: Meter illumination lamps, 3.4 Watts, SAE number 158 All other bulbs, 1.7 Watts, SAE number 161 Quote Link to comment
datzenmike Posted January 9, 2010 Report Share Posted January 9, 2010 The dash illumination on the 620 is... pathetic. I swapped slightly higher wattage bulbs in. So they are out there I just can't find a site that lists them by 157/158. Whenever I was in a wrecking yard I scooped a hand full of them. Quote Link to comment

Paint the inside of your cluster and the back of the speedo face white, it will help the bulbs reflect. Just mask well so you don't get any over spray on face of your speedo. Quote Link to comment
