Once the Lights Are Mounted, the Wiring Has to Make Sense

The controller might be under the dash, the rings might be in the doors, the roof panel might be overhead and the rear lighting may be several feet away. That is where a good lighting build can turn into a wiring mess fast. These Lit FX 3-pin accessories are here to extend, split or regenerate a compatible addressable LED signal without building the whole system out of random splices.

Pick the part by the problem you are solving. A short extension, a serviceable plug and a multi-branch signal repeater are three different jobs.

Choose the Part by the Job

3-Pin LED Pigtail Pair

Use these when you need a serviceable male/female connection for a compatible 3-pin LED circuit. They make sense for a custom jumper, repair connection or a point in the harness you may need to disconnect later instead of permanently hardwiring everything together.

Included with this variant: one male 3-pin pigtail and one female 3-pin pigtail.

1.5-Foot 3-Pin LED Extension

Use the extension when the existing compatible 3-pin lead simply does not reach. It adds about 1.5 feet between matching components without extending power, data and ground one wire at a time.

Included with this variant: one 1.5-foot 3-pin LED extension cable.

1-to-4 LED Signal Splitter / Amplifier

Use this when one compatible addressable LED data signal needs to feed four branches. This is an active signal-distribution part, not just a passive Y-cable, so it is the better way to keep the data signal organized when several rings or panels need the same controller signal.

Included with this variant: one 1-to-4 active LED signal splitter/amplifier.

1-to-8 LED Signal Splitter / Amplifier

Same job as the 1-to-4, but for a larger system. This makes sense when one controller signal needs to branch to several areas of the vehicle and you want the signal distribution in one serviceable location instead of stacking adapters.

Included with this variant: one 1-to-8 active LED signal splitter/amplifier.

SP901E LED Signal Repeater

Use the SP901E-format repeater when the addressable-light signal needs to be regenerated or distributed across a larger layout. Published SP901E specifications call for a 5–24V working range, compatible 5V-TTL signal input and the ability to cascade multiple repeaters.

For compatible single-data-wire LED families such as WS2811, WS2812B and SK6812, the SP901E format can provide up to eight signal outputs. For compatible data-plus-clock or dual-data systems, it can provide up to four outputs. It does not regulate LED voltage: output voltage follows the input supply, so the power supply still has to match the LED system.

Included with this variant: one SP901E-format signal repeater/amplifier.

Signal Distribution Is Not Power Distribution

The controller creates the lighting commands. The splitter or repeater helps carry those commands to multiple branches. None of these parts replaces a properly sized fused power and ground system.

Large multi-ring or multi-panel systems may need separate power injection even when one controller handles all of the data. Keep a common ground reference where the controller/repeater architecture requires it.

Do Not Guess the Pinout

These 3-pin plugs and extension connections are not waterproof. Keep them in a dry, protected location away from direct water and moisture.

Before connecting anything, verify LED voltage, data protocol, connector direction and pinout. Do not rely on wire color alone to identify positive, data and ground.
