They feature constant-current circuitry and transient voltage suppression to protect against electrical spikes. Available in amber or switchback versions, they offer either consistent amber light or a dual-colored output—white for low power and amber for turn signals—to suit various preferences and factory specifications.

Installation. Installation is straightforward and requires no wiring changes or modifications. These bulbs fit directly into existing 3157 sockets, making them suitable for both professional installers and experienced automotive enthusiasts.

Warranty. These bulbs include a 3-year limited replacement warranty, providing assurance of reliability and long-term performance.

Application. Designed for front turn signal use with 3157 bulb sockets. Compatibility varies by version and vehicle, including fitment for 2005-2015 Toyota Tacoma. Note that some versions have compatibility restrictions, such as HP24 switchback bulbs not suitable if the turn signals also serve as daytime running lights, and XP80 bulbs not compatible with Toyota TRD Offroad trim levels.
