Step 1a: Assemble LED light and covers

The MR B3RB car should look like this in the pre-production unit after opening the box.

Assemble LED light and covers

Proceed to install the LED lights. Follow the image sequence for assembling the front part of the car pieces:

Do NOT overtighten the screws and nuts holding the LED light assembly together. Just snug them up to the point that the lens and bumper assembly doesn't move easily.

UPDATING: Production units will not include the notch in the clear lenses

This is a pre-production prototype. We have found that it is better to install the lenses so the notch cutout does NOT clear the connector and instead sits on TOP of the connectors. This helps prevent over tightening.

The clear lenses generally have brown protective paper film that must be removed before use.

Remove brown protective film from clear lenses before use

Find the 13mm long screws in the kit of black screws included in the kit. Reuse the lock nuts that were originally installed.

See this link for clarification on the correct screws to use: https://app.gitbook.com/o/-L9GLsni4p7csCR7QCJ8/s/U93yDWZcgjXGgsC1Duqv/~/changes/153/whats-in-the-box/witb-mr-b3rb-bmf#fastener-screw-m3-x-0.5-x-5.0mm-hex-drive-button-head-s.no.-16-fastener-screw-m3-x-0.5-x-10mm-hex-dr

Use a SIMPLE Nylon nut (NOT the Nylon LOCK nut) to act as a spacer between the polycarbonate and the LED PCB. The nylon nuts will slide on the plastic allowing the screws and lock nut to be tightened later.

Note: the polycarbonate lens has a cutout, due to assembly changes, it no longer matters if this is facing upward or downward.

LED PCB goes on over top of the Screws with Nylon nuts

Connectors face up toward the slot.

Attach to frame using Nylon LOCK nuts.

Note while assembled there should be no bending of the frame or LED board. The SIMPLE Nylon nuts are acting as a spacer.

The front part of the car should appear as follows:

Repeat the same assembly process for the rear of the car. Note that the back piece is identical to the front one but slightly longer.
