Hi Brent, thanks for your message.  We designed a lighting kit several years ago for the Lowboy.  Here's the setup:

The price for this kit is $139.99.  In addition you can also add a lightbar to the trailer ($36.99) and we also have pre-built flashing warning lights for the 4 warning lights on the trailer that flash rapidly in sequence ($89.99).  We haven't actively marketed these kits yet, but if you'd like to order any, let me know and we could make one for you for January.

We have also been working on a lighting kit with rotating beacons and remote control for the crane truck:

 Price for this kit is $199.99.  Again, we could make one for you for January if interested, let us know.

Thank you again.
