Yep, I bought the manual. At that price it is worth the risk and it is very thick, so who knows what may be included.
As an old lighting engineer I know all about long life lamps. The commercial world has been full of that problem for years. Since retiring in 2000 everything has changed and I am no longer current. Yes, I "retired" at 50 and spent many years traveling as we decided where we wanted to settle. It turned out to be 50 miles from where we both were born. No' I wasn't really retired, but never held a regular job again.

BTW, I built an off grid home and every lamp in the place is LED. Lighting is no longer the biggest energy use. Now it is refrigeration.

I tried plugging a spare relay into the only space in the relay tray and got a buzz, so gave up on it for now. I suppose next I will have to figure out how to get that thing out. It looks like an impossibility. What I am hoping to do is use the fogs for daytime running and reduce the wattage in the rear, which will require some rewiring. Here DTR is not required, but still a good idea on two lane roads where nobody pays attention to the speed limit. Next I need to get into the FAQ's and figure out how to get the dash apart. The speedo needs repairing. The car came with two spares! I'm using a pretty slick app on the phone for now. Dare I tell you what it has recorded for top speed as I was passing a truck that was ignoring the speed limit? Montana is heaven.
