Why choose the TF552/536 flasher?
Consistent flash timing
Delivers dependable 60–120 flashes per minute, ensuring your turn signals remain predictable and road-legal under varying loads.
Broad current handling
With a current window from 0.27A to 14A, this unit works reliably with bulbs and LED-based signal loads commonly used across automotive and trailer applications.
Robust build & cooling
The round aluminum housing improves heat dissipation for stable operation when the unit runs for extended periods.
Easy installation
Simple 2-terminal connections make replacement fast for both DIYers and professional technicians.
Compatibility & typical uses
The TF552/536 is suitable for:
- Passenger cars and light trucks
- Trailers and RVs
- Fleet vehicles and utility equipment
Because it handles a wide current range and standard 12V systems, it’s a versatile replacement for many OEM and aftermarket flasher applications. Always confirm terminal type and mounting fitment for your vehicle before purchase.
Durability & compliance
CEC rates the TF552/536 with a 40-hour life span under specified test conditions, and it is manufactured to meet DOT compliance standards. The thermal metal design prioritizes longevity and consistent operation across a range of temperatures and electrical loads.
How to install (overview)
- Turn off the vehicle ignition and disconnect battery negative terminal for safety.
- Locate the flasher relay—commonly under dash, behind fuse box, or in the relay panel.
- Remove the old 2-terminal flasher and note terminal positions.
- Insert the CEC TF552/536 into the correct socket or connect leads to the two terminals.
- Reconnect battery and test left and right turn signals for correct operation.
If you’re unsure about compatibility or wiring, consult your vehicle’s repair manual or a qualified mechanic.

Frequently asked questions (FAQ)
Will the TF552/536 work with LED turn signals?
Possibly — the TF552/536 supports a wide current range (0.27–14A). Many LED conversions draw far less current than incandescent bulbs and may require load resistors or an LED-specific flasher to achieve proper flash rate. Test the unit after installation and, if hyper-flashing or irregular timing occurs, consult LED flasher/resistor solutions.
What does "2-terminal" mean?
2-terminal indicates the flasher has two electrical connection points (typically power in and load out). This is a common, simple interface compatible with many OEM flasher sockets.
Is this DOT compliant?
Yes — the CEC TF552/536 is specified as DOT compliant, meaning it meets applicable U.S. Department of Transportation requirements for turn signal flashers.
