All the rear lights were in poor condition, so new stop/tail lights were purchased. The plastic Lucas L760 indicators were refurbished (the bulb holders were bead blasted). One lens is cracked and will be replaced. To increase safety I intended fitting additional rear stop lights, this is commonly done in the US (see picture below). The rear panel, which was replaced in 1981, was for the pre-1970 Mk2 GT6 which didn't have the combined rear reversing/number plate assembly, and had two holes in each side for the fitment of indicators and separate reversing lights. As I didn't need the inboard holes for the reversing lights, the welder blanked these off. I intend to get these holes reinstated so I can fit the additional stop lights. The problem was which type to fit! I had three choices: to fit similar plastic L760s (modern replicas are readily available), to fit the earlier Lucas glass L594 with red instead of clear (reversing) lenses, or to replace both with Austin Healey 3000 Lucas plastic L691/2 lights which are often fitted to USA GT6s, but at 85mm diameter compared to the 73mm of the L760s are very close together. I came to the conclusion that the smaller L594 are old fashioned and did not match the later L760s fitted to the GT6 Mk2, which I think is the reason why Triumph fitted the combined reversing/number plate assemblies to late GT6 Mk2's and Spitfire Mk3s in 1970. The best choice, therefore was to fit a pair of matching replica plastic L760s with red lenses. A drawback of this is that these don't have the chrome bezel rims that the indicators have, and I can't fit them without rubber plinths, as fitted to the indicators. I have therefore purchased an additional set of chrome bezels and intend to get some plinths made (without the wedge shape necessary on the indicators), possibly by 3D printing, if I can do a drawing in Sketchup!
Above are the lights, ready for fitting. From L to R: LH Stop/Tail (L672), LH Indicator (L760), Additional Stop Lamps (L760), RH Indicator and RH Stop/Tail. The wires for the additional stop lamps will be shortened, and wired so both filaments light up when the brake is depressed, to give increased brightness.
