- Summary
- 13135 - Customer Satisfaction. Heat generated by the daytime running lamp (DRL) may deform the bulb gasket. This could cause the light reflector to crack; however, this will not affect the performance of the lamp. Dealers will install a new gasket and reinforcement plate between the socket and the reflector.
