Custer Products STR-QRLY Quad Flash LED Strobe Relay Driver

The Custer Products STR-QRLY is a compact, single-function LED strobe relay that converts any standard LED light into a quad-flash strobe light. Designed for trailers, trucks, and powersports applications, this small inline relay box is easy to hardwire and delivers a reliable, fixed quad-flash pattern for enhanced visibility and safety.

Key Features:

• Delivers a dedicated quad-flash strobe pattern — single pattern, no programming required
• Drives up to 420mA — compatible with a pair of most LED tail lights or up to a dozen LED marker lights
• Compatible with 12-volt and 24-volt power supplies
• Small, compact form factor with simple inline hardwire installation
• Works with virtually any LED light — tail lights, marker lights, warning lights, and more
• LED-only — not compatible with incandescent lights

The STR-QRLY is ideal for adding a quad-flash warning strobe effect to existing LED lighting on trailers, utility vehicles, and commercial trucks. For applications requiring multiple flash pattern options, see the companion STR-MRLY multi-function strobe relay. One relay unit is required per independent light circuit.
