Description

7507 PY21 White LED Light Bulbs With Built-In Resistors

Underground Lighting 7507 LED light bulbs provide a direct replacement for compatible 7507, PY21, BAU15S, and T20 applications. Each bulb produces 1200 lumens through 54 white SMD LEDs with 360° coverage, giving compatible lighting housings a brighter output than the factory incandescent bulb.

Built-In Resistor Helps Prevent Hyperflash

The CANbus electrical design includes a built-in resistor on the turn-signal filament only. Because the resistor is not continuously active across both filaments, the design also limits unnecessary heat exposure inside the bulb housing.

Cooling Fan and Full-Metal Heatsinking

Heat management is built into the bulb rather than relying only on the vehicle housing. Full-metal heatsinking works with the built-in silent fan to help control heat when the resistor is engaged.

The fan activates when the high filament is engaged, reducing heat around the resistor and protecting the LED from continuous thermal exposure.

Plug-and-Play Installation

Installation in the 7507 LED is straightforward and beginner-friendly. It replaces the factory incandescent bulb in 10 minutes without cutting, complicated wiring, external resistors, or additional parts.

Frequently Asked Questions (FAQ)

What is a 7507 LED bulb?

A 7507 LED bulb is an automotive LED replacement for compatible 7507 applications. This model uses 54 white SMD LEDs, produces 1200 lumens per bulb, and includes CANbus circuitry with a built-in resistor.

Are 7507 LED and 1156 LED bulbs the same?

No. 7507 and 1156 LED bulbs are both single-contact bayonet bulbs, but they use different base configurations. A 7507 uses a BAU15s base with 150° offset pins, while an 1156 uses a BA15s base with 180° opposing pins. Because of this difference, they are not generally interchangeable, even though they have similar size and function.

Will this 7507 LED bulb cause hyperflash?

The built-in resistor is designed to prevent hyperflash and error codes in compatible vehicle applications. Vehicle electrical systems can vary, so proper bulb and application compatibility should be confirmed before installation.

How much does it cost to buy a 7507 PY 21 LED bulb?

The 7507 PY21 LED bulb is priced at $64.99 per pair. You get two bulbs in the set, with each producing 1,200 lumens. Built-in resistors are included, along with a 1-year warranty.

Do you offer free shipping?

Yes. Free shipping is available on orders over $99.99.

Does this bulb fit my car?

This bulb fits vehicles that use a compatible 7507, PY21, BAU15S, or T20 bulb size and socket. It is designed as a direct replacement with plug-and-play installation, so we recommend confirming your vehicle's original bulb size before ordering.
