Finally! A solution to the problems of burnt sockets, and short bulb life in vehicles with daytime running lights! This ultralong-life bulb lasts five times longer than the 4157NA/LL. Premium pressed-glass base and high-temperature UltemŽ base collar guarantee long, heatproof performance. Their filaments are rated at 14v rather than 12.8v, and the all-glass base and Ultem collar do a better job than plastic of conducting heat away from the bulb-to-socket junction. Directly replaces the following amber wedge-base park/turn/DRL bulb types (with or without suffixes like -K or -LL): 2458A, 2458NA 3057A, 3057NA 3157A, 3157NA 3357A, 3357NA 3457A, 3457NA 4057A, 4057NA 4157A, 4157NA |
