Why Choose This Splitter For Glass is Class Gen 2?
Adding more Glass is Class Gen 2 watermelon lights should not mean hacking into your wiring. The DD4100 DT 4-pin splitter gives you a cleaner way to expand a compatible Gen 2 plug-and-play harness setup while keeping the install easier to service later.
This is the right add-on when you want to add additional Gen 2 lights to a universal kit, bracket setup, mirror light layout, frame-mounted lighting layout, or custom show-truck lighting build using compatible DT 4-pin connections.
Key Features & Benefits
Built For Plug-And-Play Gen 2 Expansion
Glass is Class Gen 2 watermelon lights now use a 4-pin DT connector, and this splitter is designed to work with compatible DT 4-pin wiring layouts. That makes it a practical add-on for expanding a Gen 2 install without cutting the harness apart or splicing in another light manually.
Always confirm the total current draw of your lighting setup before adding extra lights.
2-Way Splitter Design
The DD4100 is a 16-inch 2-way splitter wire. It includes one female DT connector and two male DT connectors, allowing one compatible DT 4-pin harness output to branch into two plug-in connections.
Standard DT 4-Pin Connectors
The DT 4-pin connector format keeps your Gen 2 wiring cleaner and more modular. This is especially useful when adding lights across brackets, bumpers, frame locations, or custom semi-truck lighting layouts where serviceability matters.
Heavy-Duty 14AWG Wire
The DD4100 uses 14AWG wire for a stronger wiring accessory than a light-duty universal jumper. This matters when you are building a clean lighting system with multiple connection points.
Over-Molded Connector Design
The over-molded connector design helps provide strain relief and protection from the elements around the connector body. This supports a cleaner and more durable wiring layout compared with loose butt connectors or exposed splice points.
Performance / Compatibility / Use Case
The DD4100 is best used as a plug-and-play expansion splitter for compatible Glass is Class Gen 2 DT 4-pin lighting systems. It is ideal for customers who already have the BTS universal Gen 2 kit with the DD4104 relay switched harness and want to add more Gen 2 watermelon lights without cutting into the harness.
Use cases include:
- Adding another Gen 2 watermelon light to a bracket setup
- Expanding a universal Gen 2 kit
- Creating cleaner multi-light layouts on pickups, semi-trucks, and custom rigs
- Keeping wiring modular for future service or changes
- Avoiding unnecessary cutting and splicing
This splitter is not intended as a standalone power source. It should be used as part of a properly fused, compatible DT 4-pin wiring system.
Installation / Fitment / Technical Details
This splitter is designed for compatible DT 4-pin wiring layouts. For Glass is Class Gen 2 installs, confirm that your lights and harness use the matching DT 4-pin connector setup before ordering.

Frequently Asked Questions
Does the DD4100 splitter work with Glass is Class Gen 2 watermelon lights?
Yes, it is intended for compatible DT 4-pin Glass is Class Gen 2 wiring setups. Confirm your Gen 2 lights and harness use the matching DT 4-pin connector before ordering.
What does this splitter do?
This splitter branches one compatible DT 4-pin connection into two DT 4-pin outputs. It helps add another compatible Gen 2 light without cutting or splicing the harness.
Do I need this if I am buying the universal Gen 2 kit?
You may need it if you want to add additional Glass is Class Gen 2 lights beyond the standard universal kit layout. The universal kit includes the relay harness and bracket, while this splitter helps expand the system.
Can I keep adding splitters to run more lights?
Do not keep adding lights without checking total current draw and harness limits. Extra lights should stay within the safe capacity of the harness, fuse, switch, and wiring setup.
Does this splitter require cutting or splicing?
No cutting or splicing is required when it is used with compatible DT 4-pin Gen 2 connectors. It is designed for a plug-and-play connection.
Will this work with older Glass is Class watermelon lights?
Older hardwired Glass is Class lights may not use the same DT 4-pin connector. This splitter is intended for compatible Gen 2 DT 4-pin setups, not older hardwire installs unless the wiring has been properly adapted.
Can I use this on a 24V truck?
Do not assume this splitter is 24V compatible. Diode Dynamics lists this splitter at 9–16V, so 24V builds should be confirmed before installation.
