Rear lights in series doesn’t work – far too dim! So plan B needed. The
brake light bulbs (middle ones) are 21w so they should be bright
enough. I’m just worried that its not obvious enough of a difference.
Did a bit more tonight – put some more P clips in on the brake lines at
the front of the car and zip ties where I couldn’t get P clips in. Also
zip ties all the electrical cable around the bottom of the engine bay.
Finished off by trimming back the scuttle above the gauges so the fit
in properly!
