not sure but i head of these speed warning dashes . what are they exactly ? the reason i ask is i was testing my wiring on the 72 and i noticed a red light at the 50 mile per hour mark . Is this considers a speed warning dash or did someone switch out the high beam bulb . I looked at my other clusters and they dont have a light there just a space for one .just curios thanks. sorry no pic i actualy lost my camera duh
