Two types are available to match the door shape.

Two types are available to match the door shape: "replacement type" and "adhesive type".
The SR-DWL01 is designed to be a replacement for the front door covers and reflectors, as well as the door covers and reflectors of some rear sliding doors on Toyota and Lexus vehicles.
The SR-DWL02 is designed to be used by attaching it to various doors, rear gates, etc. of other vehicle manufacturers.

Easy installation! No complicated wiring required! SR-DWL01

■SR-DWL01 Front Door Replacement Installation Overview

① Check the cover or reflector on the door. (The part to be replaced is the φ23 hole.)
② Remove the cover and reflector. Install the SR-DWL01 unit so that it covers the φ23 hole.
③ Attach the included magnet to the product body, which is fixed when the front door is closed, at a point where it is 20 mm or less away from the door. *Caution: Door interference may occur. Cleaning and degreasing of the attachment surface is essential.
④ Confirm that the unit attached to the door turns off and flashes when opened and closed due to the magnet, and then the work is complete. *Perform the same procedure on both sides. Remove the insulating film from the unit and check. *Photo is of an MZRA90 Noah.
★When installing the general-purpose adhesive type (SR-DWL02), the procedure is the same except for the adhesive application. Temporary attachment of the double-sided tape is essential until the position is finalized. (Strong double-sided tape)

④ Confirm that the main unit attached to the door turns off and flashes when opened and closed, due to the magnet. Finally, securely fasten the temporarily attached double-sided tape. *Perform the same procedure on both sides. Remove the insulating film from the main unit and check. *Photo is of an MZRA90 Noah.

Product dimensions

General installation precautions

The flashing will stop when the distance between the product body and the magnet is 20 mm or less, as shown in the diagram above. When installing in a vehicle, please ensure that neither the product body nor the magnet interferes with the door when opening or closing, and that the flashing and turning off functions reliably.
