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 4157LL. 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 wedge-base park/turn, brake/tail, and DRL bulb types (with or without suffixes like -K or -LL): 2458, 3057, 3157, 3357, 3457, 4057, 4157 (with or without suffixes like -K or -LL) |
