Tridon Hazard Warning Flasher

Tridon Hazard Warning Flashers: Reliable Signaling You Can Count On

When it comes to keeping drivers safe on the road, few components carry as much responsibility as the hazard warning flasher. Hazard warning flashers are the small but critical relays that control the rhythmic blinking of your vehicle's emergency indicators — alerting other drivers to stopped vehicles, roadside emergencies, and lane changes gone wrong. Tridon has built a well-earned reputation as a trusted name in this category, offering a comprehensive lineup of flasher units engineered to meet or exceed original equipment standards.

Three Technologies, One Mission

What sets Tridon apart in the hazard warning flasher space is the breadth of its relay technology. Tridon's flasher relay catalog spans electro-mechanical, electronic, thermal, and LED-compatible variants — meaning there's a purpose-built solution for virtually every vehicle type and lighting configuration. This variety matters: as more drivers upgrade to LED turn signals and hazard lights, the need for a compatible flasher relay becomes critical to preventing the dreaded "hyperflash" (rapid blinking caused by the low current draw of LED bulbs).

These original equipment replacement flashers feature integrated circuit-controlled reliability, and most have built-in lamp outage indicators — a feature that has become standard on nearly all modern cars and light trucks. The built-in lamp outage warning is particularly valuable: when a bulb fails, the relay automatically increases the flash rate to alert the driver before a safety issue goes unnoticed.

Key Product Lines

Tridon's hazard warning flasher lineup covers a wide range of terminal configurations and voltage ratings. Notable models include:

• EP Series (Electronic Flashers) — the EP series features a downsized form factor with a precise square wave I.C. controller, high-temperature plastic enclosure, solid state relay driver technology, and highest OEM-quality printed circuit board materials, with a safety warning via fast flash rate when one lamp fails. Models like the EP26, EP27, EP29, EP33, EP34, EP35, and EP36 cover a wide range of domestic and import vehicles.
• EL Series (Electro-Mechanical Flashers) — the EL13 and EL12, for example, are electro-mechanical flashers designed to replace specific OE/OEM part numbers, offering reliable and efficient performance for car and truck lighting systems.
• Thermal Flashers — Tridon's electrical lineup also includes thermal flashers , catering to older vehicles and heavy-duty applications where simplicity and durability are the priority.
• LED-Compatible Units — certain Tridon flasher units allow bulbs and LEDs to flash normally, without resorting to load resistors that would draw the same current as filament bulbs — a significant advantage for enthusiasts upgrading classic or modern vehicles to LED lighting.

OEM-Grade Engineering for Every Application

Tridon's electronic flashers meet or exceed D.O.T. requirements and are designed for current-model domestic vehicles, accommodating both 2-lamp turn signal and 4-lamp hazard flasher applications, as well as trailering use. Tridon flasher relays are available in two packaging styles: blister packed for retail and self-serve environments, and boxed for trade and high-volume applications — making them equally at home on a shop shelf or in a professional service bay.

Flasher units are designed to control the flash rate of vehicle directional indicators by providing regular interruption of the electric current in the indicator circuit — and Tridon's engineering ensures that interruption happens with precision, every time. Whether you're restoring a classic truck, upgrading a daily driver's lighting system, or simply replacing a failed relay, Tridon's hazard warning flasher range offers a solution built to last.
