Ecocstm’s 60 LED interior kit provides bright, energy-efficient lighting with a long service life. The kit uses high-quality chips and a clear lens to evenly illuminate van interiors, aiding safety and comfort. Installation is straightforward thanks to a strong double-sided tape backing, with optional screws for extra stability. The lights are designed for direct connection to a vehicle’s 12V system and allow for easy customization by cutting and wiring each module as needed. No relays or transformers are required, simplifying upgrades for DIY enthusiasts.

The housing is waterproof and dust-proof, protecting copper wiring inside for reliable electrical conductivity. They are designed for plug-and-play installation, with pre-wired features that avoid cutting or splicing of the original wiring. Suitable for a wide range of vehicles, these adapters can help upgrade lighting systems in Jeeps and other popular models, with verified compatibility across several Jeep Wrangler configurations and similar platforms.
120 Led Van Interior Light Kit
This 120-LED interior kit expands on the 60-LED option with additional modules for larger vans or more complex layouts. The lighting system maintains high brightness and energy efficiency, offering a long service life and straightforward DIY installation. Modules are designed for customization, allowing you to tailor light intensity and coverage in cargo spaces, living areas, and overhead compartments. As with the smaller kit, no relays or transformers are required, streamlining the upgrade process for many van builds.

It’s designed to reduce interior heat load and improve acoustics while providing a clean, modern look. This kit can be paired with other van upgrades to create a cohesive interior renovation, particularly in cabinetry-integrated layouts and ceiling modules for a more polished finish.
Buying Guide
Key purchase considerations for modular van conversion kits include compatibility, installation effort, durability, and future expandability. Consider the following:
- Vehicle compatibility and standards: Ensure adapters and connectors match your van’s refrigerant type, port sizes, and electrical system voltage (commonly 12V in vans).
- Materials and durability: Aluminum, copper, and ceramic components offer corrosion resistance and longer service life in harsh or variable climates.
- Ease of installation: Plug-and-play options save time and reduce the need for specialized tools. For lighting, look for DIY-friendly modules with strong mounting options.
- Maintenance and sealing: Sealed components protect against dust, moisture, and contaminants that could affect performance.
- Modularity and future upgrades: Choose kits that can be expanded or reconfigured as your needs evolve, especially for interior lighting and electrical systems.
- Warranty and support: Favor brands that provide clear warranty terms and reliable customer support for troubleshooting and replacements.
In terms of performance comparisons, lighting kits typically balance brightness and energy use, with DIY-friendly installation being a strong plus. Refrigeration adapters prioritize durability and compatibility with common R12/R134A systems, while valve kits emphasize accurate flow control and ease of use for converting old refrigerant lines. For van aesthetics and comfort, headliner and interior upgrade kits offer substantial improvements with manageable installation timelines. When selecting, weigh how each component complements your overall van plan—electric system, climate control, and living space configuration.
