DAS UNDER-LIGHTS

GROUP BUY: DAS UNDER-LIGHTS

What’s going on?

GMR is R&D'ing products to address issues we experience while offroad racing. Perhaps we can help you too. Help GMR make products, and we'll make them good. Our goal is to learn enough in group buys to make future, full blown products.

The owner of GMR is a degreed Welding Engineer, and this Group Buy is his engineering attempt to meet our community’s need to modernize aging vehicles.

This is equal parts engineering effort, product design, supply chain management, and intro to additive manufacturing.

What are the Under-Lights?

These are 3rd gen 4runner specific products to replace turn signals. These mount underneath the headlights. They replace the stock turn signals with an amber, white, or switchback lightbar. They replace the stock headlight's steel filler plate with features that improve both function and form. Whenever an aftermarket bumper is installed, this provides a clean solution to retain front turn signals and/or running lights.

Will there be upcoming group buys for more vehicles? Yes! Current list:

  • 1st Gen Tacoma

  • 4th Gen 4runner

  • 1st Gen Sequioa

Variations of Das Under-Lights

  • Amber, White, or Seqential LED's which include both Amber and White.

  • The filler plates are unique to the LED Type. Sequential LED's have their own filler plate design that's not backwards compatible with basic Amber and White LED's. The design and manufacture of these steadily improve overtime. What was sold in the group buy in September is fundamentally improved compared to parts shipped out in August. That's how fast this is improving.

  • Hardwiring: Cheapest, but the most difficult. You have the knowhow to wire/ splice these up yourself with your tools and equipment.

    OEM Plug N Play: The easiest, but more expensive. OEM style plugs are soldered in so you can splice the LED's into your turn signals or into the marker lights. Can be used in parallel with your current lights. Varies by model year. We solder these up for you, so choose wisely.

    Load Resistor Upgrade: The laziest, but most practical. You get the OEM Plug-N-Plays with load resistors to stop hyper-flashing. We do not recommend the load resistor upgrade. See the installation instructions below.

    EP 35 Relay upgrade: This is a common relay at any autoparts store, like AutoZone or O'reilly's. You can order from me go get it yourself.

Installation Instructions

  • The Under-Lights are delivered bare, uncoated. Paint, Primer, or Wraps help the 3d printed parts last. Make it your own at this stage.

  • Remove the grill from the 4runner.

  • This is the trim piece the Under-Light replaces. Remove the plastic clip on the fender side. Do as you will, but ideally, this filler plate is history.

  • Remove the OEM headlight assemblies. There are four bolts that mount each one to the SUV body. This necessary if your bumper does not give access to the fender trim bolts. Tubular bumpers are probably ok, but any full plate bumper or OEM bumper will not do so. If your truck is stock, remove the headlight assembly.

  • The 4runner has a bolt that mates the fender to the front of the SUV's body. Remove that bolt. Mount the Under-Light with that bolt, finger tight. Align the Under-Light to the fender trim piece by raising it up or down. Then, tilt the Under-Light body to match the bodyline of the bumper. How tight? 1/4 turn after snug. If you hear cracking, it's fine. If you see cracking, let me know and I'll take care of you.

  • If you're trying to match the body line perfectly, shim the body in or out as necessary. Later revisions are shipping with LEGO-like shims that snap into place for you to get the ideal match. If yours does not come with shims, use a heat gun to gently bend the wing of the Under-Light to your preferred point.

  • Mount the headlights, tighten down the four bolts per OEM specs.

  • This one screw is the reason why you have to take off the grill. Be gentle, it's a plastic-plastic connection that won't take much torque to cross thread.

  • There's three kinds of wiring:

    • Hard Wiring

    • Plug and Plays

    • Plug and Plays with Load Resistors

  • If you have not converted your 4runner to run LED's yet, the truck will think it's bulbs are out and flash them quickly. How do you fix this?

    Consider upgrading the turn signal relay with an EP35 relay. This will require removing your dashboard. If you don't want to do that:

    Use the plug and play, which allows you to use the OEM turn signals as the hyper flash fix.

    Use load resistors: either wire them in yourself or reach out for a custom solution that plugs into the plug and plays. This is not a preferable solution, because resistors take more current than the OEM lights do.
