Placing Christmas Lights on Roof

Oh yeah - one thing -
When you try the 12v, if it doesn’t work, just try switching the lines. I got one of those Thule license plate holders with a light (I use it on the ladder, since my plates are covered when I have the bike rack on). Put on the DTP connector and couldn’t figure out why it wasn’t working. Last ditch effort I just switched the lines (so it was red to black and black to red) and it worked fine. Beats me, but “whatevs” as the young people say. We’re all looking forward to seeing the pictures!

One last thing - lights on a moving car on the road. F?!&%#g kill joys.

Yes I tried that swap of lines. No dice. Thanks for the note on the laws. I also flip my front license plate up ( no no in Mass) on this and other cars. Haven’t been stopped yet. I figure it’s worth the price until the first ticket.

I figured since you were in Boston - a communist enclave that literally outlawed the celebration of Christmas at one point - I should point out the lighting regulations.

OK, finally figured out the Christmas lights. Because I wanted to use the roof switches I had to order 12 V lights which came with cigarette lighter plugs. I clipped those off and put on Deutsche DTP‘s. It turns out even though there’s no indication on the wires, There is a negative and positive wire on the Christmas lights. Once I figured that out it was a snap. Love using the roof toggle. And realized you can have the vehicle off flip the power switch on the roof and the exterior switch and they light up.
