WLJH 74 T5 LED Dash Bulbs - Purple Pack of 20, 100 Lumens, Fits T5/2721/286 Wedge Sockets

WLJH 74 LED T5 dash bulbs are compact, ultra-bright purple T5/74 wedge LEDs designed to replace instrument cluster and dashboard bulbs for clearer, longer-lasting illumination.

These WLJH replacement bulbs use three 3030 SMD chips arranged to cast light upward and to the sides, producing about 100 lumens at 12V for a vivid, even glow. Sold as a pack of 20 in a purple color, they are compatible with a wide range of wedge-style sockets (including T5, 2721, 286, and 74 series) commonly found in cars, trucks, and motorcycles. The bulbs are polarity-sensitive and intended for dash lights, gauges, indicator lamps, and other small in-cabin light fixtures.

How bright are these WLJH 74 T5 bulbs compared with stock bulbs?

Each bulb delivers approximately 100 lumens using three high-efficiency 3030 SMD chips, producing a much stronger output than many older SMD chipsets. The dual-side and upward-facing LED layout helps the light spread evenly across lens surfaces and gauge faces.

• Rated around 100 lumens at 12V
• Three 3030 SMDs for superior intensity
• Broad light dispersion: one up, two side-facing LEDs
• Noticeably brighter than 5050/2835/3528 chip variants

Which sockets and instrument lights will these replace?

These WLJH bulbs are made to fit many wedge-style connections found in instrument clusters and accessory lights. They work with common bulb numbers and socket types used across many vehicle models.

• Compatible with T5/74, 2721, 286 and related wedge sockets
• Fits bulb sizes: 17, 18, 24, 27, 37, 58, 70, 73, 74, 79, 85, 86, and similar
• Use in dash gauges, clock lights, radio dials, and indicator lamps
• Check original bulb number or measure socket before installing

Is installation difficult and what should I watch for?

Installation is straightforward but requires attention to polarity and socket handling. These LEDs are polarity-sensitive, so they will only light when the positive and negative are aligned correctly.

• Push the bulb into the wedge socket, then rotate the socket into place
• Do not pull the LED out of its housing once seated
• If it doesn't light, remove, flip 180°, and reinstall
• Confirm fit and polarity before final assembly of trim pieces

What are the practical uses and limitations of WLJH purple dash bulbs?

These bulbs are tailored for interior accent and functional illumination where a colored dash or indicator light is desired. They are not intended as exterior headlights or for circuits requiring specific CANbus resistors unless additional components are used.

• Ideal for instrument clusters, indicator lights, and consoles
• Good for show vehicles or those wanting a purple interior accent
• Not a direct replacement for high-current exterior lighting
• Confirm electrical compatibility for vehicles with bulb monitoring systems

Who is this for: This pack of 20 WLJH 74 T5 purple LEDs is suited for car and motorcycle owners, customizers, and repair shops updating interior indicators, clocks, and dash clusters. If you want brighter, longer-lasting purple illumination for gauges or small in-cabin fixtures and you can confirm socket size and polarity, these bulbs offer a reliable upgrade. Avoid use in circuits that demand specific load resistance or in exterior applications requiring weatherproof housings.
