1 600-859 Red Diffusers for Type D, peanut bulb, 4 pack $3.01 $3.01


What you do here is remove the climate control bezel (remove the 3 knobs and 2 screws, then pull it off), unscrew the 4 screws that hold the DIN gauge harness. Carefully unclip the small wiring harness from each gauge and unplug the vacuum hose from the boost gauge. Gently remove the rubber bulb plug from the gauges and use a pair of needle nose pliers to carefully twist each bulb socket from the rear of each gauge. Install a small red diffuser on each bulb, then install a larger one over the small one. Carefully install each bulb such as not to let the larger diffuser slip off. You must use both diffusers, as one diffuser causes the gauges to be bright pink. With two diffusers, the gauges will match the climate control, clock, lighter, etc. *perfectly*. You won't believe how well it matches - looks like it came that way.
