White/Amber Switchback LED Bulb

The Riglow™ White/Amber switchback bulb is listed for white running/parking illumination and amber turn-signal operation in compatible lamp circuits. Sold individually; order two for a pair.

Check your socket option

Saved options are 1157 / BAY15D and 7443 / T20 / WY21W. These labels do not establish interchangeability or direct vehicle fit. Confirm contact configuration, connector geometry, polarity, circuit functions and housing clearance.

Confirm operation and ratings

White-to-amber switching, priority and return-to-white behaviour require supplier confirmation for the selected bulb and vehicle circuit. Earlier 28W, up-to-2500-lumen, voltage, current, distribution and lifespan claims are preserved as unverified notes in the linked specifications, not confirmed electrical limits.

CANBUS compatibility, warning-free operation, hyperflash prevention, flicker elimination, constant-current circuitry, internal fan and aluminum heat-sink construction require confirmation. Cooling, lifespan and safety improvements are not guaranteed.

Installation and package

Follow selected-bulb and vehicle instructions. Plug-and-play installation is not established; do not improvise pinouts, polarity changes or load-resistor/decoder wiring. Consult a qualified installer when uncertain.

Listed package: 1 White/Amber switchback LED bulb. Additional components or accessories are not established.

Saved options: 1157 / BAY15D and 7443 / T20 / WY21W; option labels do not establish interchangeability.

Installation

Confirm selected variant's supplier instructions and vehicle lamp circuit, contacts, polarity, clearance and switching requirements; plug-and-play installation is not verified.

Fitment

No vehicle-specific direct fit is verified. Earlier 1157/2057/2357/7528/P21/5W/BAY15D and 7443/T20 application references require contact, mechanical and electrical checks. Do not assume WY21W or other socket labels are interchangeable.

Notes

Listed package: one White/Amber switchback bulb, sold individually; order two for a pair. No additional decoder, resistor or installation accessory is established. Captured original claims: 28W, up to 2500 lumens, 9–16V DC, 2.3A, 360-degree distribution and 30,000+ hours lifespan. These are unverified; rating basis, measurement conditions, current demand and electrical limits need product-specific supplier evidence. Do not substitute the mismatched 25W multi-colour LED record's ratings or two-bulb package. White running/parking/position illumination and amber turn-signal switchback are listed functions. Confirm supported lamp functions, control circuitry, switching priority and return-to-white behaviour for the selected variant and vehicle; automatic switching is not verified. CANBUS/error-free, anti-hyperflash, flicker elimination, constant-current driver, internal fan and aluminum heat-sink claims require supplier confirmation. No warning-free operation, cooling performance, improved safety/visibility or extended service-life guarantee is established. No supplier-confirmed CANBUS or fan flag is inferred. Use the selected bulb and vehicle instructions. Do not improvise pinouts, polarity changes or additional load-resistor/decoder wiring. Separately linked product warranty and general LED installation-planning guidance remain product-specific references.
