The total cost for the lighting upgrade Kit is $749.  The $400 is for the deposit to get the lights and harness ordered from Baja Designs.  The S2 Pros sell at $421 for clear and $441 for amber alone for the kit with the harness, so we are collecting this to start each customers project.    
 
Thank you for your interest in the Grenadier back up light configuration utilizing the Baja Designs S2 Pro lights.  For this project it is required for you to remove your plastic bumper covers and the brackets underneath and send them to us for modification.  This is simple, using a Torx T30 driver to remove four bolts.   Ship these to Design Build Go address listed below. 
You will have to place a deposit for the lights to be ordered.  I can provide either clear or amber lenses.  Select AMBER or Clear below.   There is a option to obtain both lenses, which are removable for an extra $50. Please call me for both.  The deposit pays for the lights and the Baja Designs harness that will be used for the installation. 
If takes about two weeks, to obtain the lights and modify the parts.  This could happens sooner.  I recommend sending the brackets and covers to me with USPS one price box with tracking or UPS or FedEx.  The quicker you send in the parts, the better. 
The deposit is $400 and the balance  of $349 will be billed when the complete parts are ready to ship.   The installation of the system is covered in this YouTube video.  https://youtu.be/wsuebqchhOw?si=mfbRZAHAb3932TuP
You can clearly wire this up in the interior of the vehicle as well.  The kit will come with the BD harness, extra wire for the long run to the front of the truck, braided wire loom, heatshrink, butt connectors and an inline mini fuse link with a 5 amp fuse. 
If you have any questions please call me at 704-682-9323.
 
You can add reflective tape back to your bumper if required by laws in your area.  I have hooked these up to my INT 2 switch but you are welcome to connect how best fits your Grenadier.
