Custom Dynamics® Turn Signal Isolator (TSI) electronically isolates all turn signal outputs from the vehicle allowing for the use of almost any aftermarket turn signal. Using the TSI, the additional turn signal load is placed entirely on an auxiliary power source and does not affect current draw on the motorcycle’s turn signal circuit. There are no relays or other mechanical devices that are subject to mechanical failure.  A short circuit on any accessory connected to the TSI outputs will have no impact on the vehicle preventing damage from non-compliant aftermarket accessories, diagnostic trouble codes, and to help protect factory warranty.

The TSI is a hardwire installation on any motorcycle and is recommended for use any aftermarket turn signal such as Custom Dynamics® Plasma Rods™ or LED License Plate Frames including LED or incandescent bulb products.
