Turn Signal Isolator Universal by Custom Dynamics

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.

Use Posi-Tap™ and Posi-Lock® connectors (sold separately) for a hassle free installation. Custom Dynamics® recommends the installation of an in-line fuse  when power is being accessed from the positive battery terminal.

Alternatively, use Custom Dynamics® Dynamic Load Isolator (DLI) for a completely plug and play solution to isolate all outputs from the vehicle.

Note: Additional CanBus Adapter (1 per turn signal) or Signal Stabilizer™ (1 per bike) may be required when stock turn signals are removed for custom applications. Sold separately.
