I would like to know if I can replace the LED on my radar detector remote controller with a high power one without changing the circuit board components.

Attached is the board and I'm looking to replace the "Alert LED" with this one:

  • Brand: Chanzon
  • Power: 3 Watt (Max)
  • Emitting Color: Natural White (4000K-4500K)
  • Recommended Current: 600mA
  • Forward Voltage: 3.0-3.4V
  • Luminous Flux: 260-280LM

Schematic of radar detector remote controller

  • \$\begingroup\$ You will be unlikely to find a direct replacement for the led without knowing how much current is available from the source detector, without adding on a small circuit. That relay isnt necessary, but you could put an opto transistor in parallel with the existing led, and a small power transistor and regulator as a led driver. \$\endgroup\$

  • \$\begingroup\$ Im trying to avoid doing the following as it will be way to bright in my eyes at night. i.sstatic.net/QIqHD.jpg is there an easy way to wire just one of those led to the current circuitboard? \$\endgroup\$

  • \$\begingroup\$ You have lost me. Your question is about installing a very bright light. Your comment is about making it less bright. Ehm, ... \$\endgroup\$

  • \$\begingroup\$ The image in the second comment uses 3 LEDs. I wanted to see if i can get away to use just 1 in place of the current "alert led from the firs schematic" and without making an addition circuitboard. \$\endgroup\$

  • \$\begingroup\$ I don't know. We don't know what's feeding the RJ11 connector. \$\endgroup\$
