Chang'an BenBen/CX20/Eado Reverse Light Switch 3729610-MR510A0 Reliable Contact Trigger

Chang’an BenBen, CX20, and Yidong reverse light switch 3729610-MR510A0 installed on the transmission housing to detect when reverse is engaged and trigger the light, while also providing a signal to reverse radar. Installation difficulty is low; about 0.3 hours of labor. Be sure to avoid transmission oil leakage. If the reverse light does not illuminate, flickers, or radar has no response, it is typically due to worn internal contacts or failed springs; replacement ensures night reversing safety.
