I recently added a second repro taillight to my 29 Briggs blindback (right side). (The left one is original and very nice.) I bought dual element socket inserts from napa and put them into the same socket as was in the taillights. It requires drilling a hole into the side of the socket in the right spot so that the tab on the insert is held properly. Make sure to figure that the spring will be depressed when the bulb is in. The new bulbs (napa also) have 2 alignment pins rather than the stock 1 pin bulb so I just touched the one pin with a grinder and removed it. It works very good. The bulb is easy to change out and fits perfectly. Its nice and tight in the socket too. I used the bright element of the bulb for the turn signal and the less bright one for the brake light. It works very well and is nice and bright on even the most sunny day. The bulbs I got at napa were higher CP than stock I think too.... On the front I bought some new "Beehive" lights from Napa and used a set of original license plate to light bar brackets and set them in real close to the headlights, they look good and work awesome, are very bright. I used the original style cloth wire loom from Mac's and ran it into the light grommet on the radiator housing, looks real nice. I couldn't get them in 6 volt so had to replace the bulbs but that was no problem. I was using a toggle switch mounted under the dash but yesterday I was at a fleemarket and bought a vintage turn signal switch and just installed it last night. One thing I also did, as I am prone to forgetting the turn signal on, is put a little piezo buzzer across the flasher terminals so when the signal is in use, I get a pleasant little "beep, beep, beep..." I used 2 diodes in the signal switch to tie in the indicator light. It flashes with either right or left turn. I don't have emergency flasher function on this switch but I don't need it. My A is completely original and I hated to mess with adding this to it but no one knows what a hand signal is anymore! People think you're waving at them and go screaming past you on the left just as you're trying to make a left turn. Its dangerous without signal lights in this day and age.
