Additional Notes

The Harley-Davidson FLHTC Electra Glide Classic uses the 3157 bulb across all listed model years, spanning 2007-2013.
The 3157 is an ANSI-standardized bulb type recognized across the United States and Canada, ensuring consistent availability in both markets.
The 3157 is a dual-filament bulb, meaning it contains two separate filaments within a single housing. One filament operates at 27W for the brake or turn signal function, while the other operates at 7W for the running light function.
The bulb follows the T25 wedge form factor, which refers to its tapered plastic base that locks into the socket without a separate metal bayonet or screw fitting.
The 3157 operates on a 12V electrical system, consistent with standard 12-volt motorcycle electrical architecture.
Because the 3157 is dual-filament, substituting it with a single-filament equivalent such as the 3156 would result in the loss of one lighting function, making direct replacement with the correct bulb type necessary for proper operation.
