Combination Rear Light / Tail Light : LED | HELLA 2SD 343 390-401

Regarding LED technology multi-function lamps In connection with these low powers, which are very different from bulb versions, there can be problems with the bulb failure check during operation on various traction vehicles. Since indicator failure checks are required by legislation, we recommend only operating the light in combination with an indicator control unit part no. "5DS 009 602-¿, 5DS 009 552-¿ or LED flasher unit 4.. 009 492". In addition, further lighting functions are detected by some traction vehicles. This is a vehicle comfort function which is not required by legislation and does not release drivers from their obligation to see for themselves that the lighting equipment is working. Here, too, faulty diagnoses can be a result of the lower power levels involved (instrument panel in the driver cab indicates a bulb failure although the function is working). Operation of the light with alternating current or pulsed direct current is not permitted! The functional ability of these light failure checks can only be established by the vehicle manufacturer. The individual light functions may only be operated with a vehicle fuse of max. 3A. In the case of onboard current limitation with the values specified above by the onboard control unit an additional fuse for the lamp is not required. Regarding flasher lights with LEDs with active electronics In connection with these low powers, which are very different from bulb versions, there can be problems with the bulb failure check during operation on various traction vehicles. Since indicator failure checks are required by legislation, we recommend only operating the light in combination with an indicator control unit part no. "5DS 009 602-¿, 5DS 009 552-¿ or LED flasher unit 4.. 009 492". Operation of the light with alternating current or pulsed direct current is not permitted! The individual light functions may only be operated with a vehicle fuse of max. 3A.
