This was all Marty's fault........
This whole melted lens thing got me thinking (That's always a dangerous thing) and after asking a couple of discreet questions on here I sprang for a set of red LED bulbs (1156 and 1157 short profile) for my Tear drops. Got 'em at NAPA, same price as Autozone/Advance (Sorry, Jim, no Pep Boys around here), Nice, short form-factor, wicked bright, and that's when the fun began.....
Installed them, tried them out and everything worked just as before - Nice, bright, Red color, same blink rate and everything. Yay! An easy score!
Except...not so fast. The dash lamp didn't blink...... It would blink once and go out and that was it while the outside lights kept blinking away. I'm running one of those way-over-designed OEM VW Directional Flasher/Emergency Flasher combos found on ONLY 1969 USA Sedans. It samples the current draw of the lights in the circuit and if a lamp burns out, it causes the dash light not to blink (even though the remaining outside lights still blink the same). It apparently is LED agnostic, or worse. It might be downright hostile to LEDs, I don't know.
So off to NAPA I went, and got a pair of LED Flasher Fixup Resistors (from the "HELP! Make-it-work 5000 collection), which tell the consumer in LARGE BOLD PRINT that in normal operation "This resistor will get hot. Firmly mount it to a steel surface and keep away from flammable objects. This part is for OFF-ROAD USE ONLY!" My "Tim-the-Toolman" side was already grinning.
I found a spot under the dash, on the bottom of my behind the dash, cross-frame member to mount them and then messed around with the wiring rats nest with all of those nasty, snipped ends of tie-wraps that are holding everything together and raking my hand and arm. Finally, I found the terminals for the left and right lights (up close to the emergency flasher switch which, BTW, is up above the radio where you can't see diddly) and wired those resistors in.
Finally! The damn thing works like it's supposed to, AND it won't melt my lenses! All told, most of an afternoon, including that second trip to NAPA.
This was all Marty's fault for giving me the idea in the first place. Me and my scratched-up hand and arm hate you.
But my lights look nice.......
