Toyota Supra MK4 Switchback LED Turn Signals 1992-1998

A switchback LED turn signal upgrade for the Toyota Supra MK4 (JZA80), model years 1993–1998. The LED board adds a white daytime running light and an amber switchback turn signal to the factory front turn signal housings (Toyota part no. 81510-80086). Choose the DIY board kit, or let us do the work with a fully modified, ready-to-install housing.

Choose your option

• Modified Housing – Clear Lens — a complete housing with the LED board already installed. Fully assembled and ready to mount on the car; no housing modification required.
• Modified Housing – Smoked Lens — the same pre-built, plug-in housing finished with a smoked lens for a darker, more aggressive look.
