Overview
Set of 2 RUIANDSION BAY15D 1157 P21/5W 24 V LED Car Bulbs Warm White Clear Round Bulb Two Levels of Lighting For Car Lights

Set of two RUIANDSION LED car bulbs with a BAY15D bayonet base and marked 1157 or P21/5W replaces the original bulbs of the same type in car lights. The marking P21/5W corresponds to a dual-filament design, meaning one bulb provides two levels of lighting. The parameters indicate a power supply of 24 V, which is suitable for the electrical system of commercial and utility vehicles, and the light colour is warm white. Inside the clear round bulb, there is a carrier with chips mounted around the perimeter and on the top surface.

Main features:

  • BAY15D base — bayonet design intended for BAY15D sockets, thus a direct replacement for the original bulb without searching for another base type
  • Marking 1157 and P21/5W — common markings for this type of bulb, which can be used to verify compatibility with the socket in the vehicle
  • Two levels of lighting — the P21/5W designation belongs to a dual-filament bulb, so one unit handles both functions, eliminating the need for two separate bulbs
  • Power supply 24 V — the value from the product parameters corresponds to the electrical system of commercial and utility vehicles, which the manufacturer accounts for
  • Warm white colour — the light colour specified in the parameters, close to that of the original filament bulb
  • Chips around the perimeter and on top — chips are mounted on the carrier from all sides and on the top surface, allowing light to emit sideways and upwards
  • Clear round bulb — the transparent spherical cover allows light to pass in all directions and reveals the internal arrangement of the chips
  • Metal base — the cylindrical part has a metal surface and connects directly to the edge of the bulb
  • Two side projections — projections on the base serve to secure the bulb in the socket, and the bulb rotates upon insertion
  • Easy replacement — the bulb simply slides into the socket and rotates, requiring no tools or modifications to the wiring
  • No cable and no external electronics — the bulb forms a single unit and no separate casing extends outside the light
  • Compact design — shape and size are based on the original bulb of the same type, ensuring it fits in its place
  • Set of 2 — the package includes two bulbs with identical parameters for both the left and right sides of the vehicle, eliminating the need to purchase a second unit
  • Spare part — suitable as a replacement for a worn-out bulb with a BAY15D base in car lights

Contents of the package:

  • 2x RUIANDSION BAY15D 1157 P21/5W 24 V warm white LED car bulb

LED car bulbs with a BAY15D base serve as replacements for original bulbs in car lights and can be inserted directly without further modifications. The dual-filament design P21/5W means that one unit covers two levels of lighting, so there is no need to deal with two separate bulbs. Chips mounted around the perimeter and on the top surface emit light sideways and upwards, maintaining light distribution close to the original solution. Before purchasing, it is advisable to verify that the socket corresponds to the BAY15D design marked 1157 or P21/5W, and to account for the 24 V power supply as per the product parameters. Two units are supplied so both sides can be replaced at once, ensuring consistent light colour.
