This unit is built into the 1967-68 Solid State Sequential Upgrade kit we sell so it is not needed if you are buying the all inclusive unit. This is a solid state unit and unlike the originals that have moving parts, this unit should never fail.

Also know that this unit is eliminated when you purchase our new, all inclusive solid state turn signal unit.
