B-Man Posted February 29 Share Posted February 29 I've been contemplating the LED headlights for a while. Getting older, I just want more light in front of me at night. But of course I don't want to blind people, which is why I'd hadnt made the conversion up until now. Last week I came across a cool video on one of the first gen Facebook forums of "switchback" LED bulbs for turn signals. The idea is that when your headlights are on, the turn signals provide another bright white light bulb up front - more light!!! And when the headlights are off, so are the turn signal bulbs. When you use your turn signals the lights switch to yellow - cool!! So when the headlights are on, and you use your turn signal, the white light goes away and the bulb blinks yellow on and off. And when the headlights are off, they just blink yellow when using the turn signals You do lose the yellow lights up front when the headlights are on. Until of course you use your turn signal. I also bought some bulb-less 7in bezels for the headlights and installed LED light bulbs. They are pretty bright compared to the Wagner bulbs I recently bought off RockAuto. Below are some pictures of the conversion. You can see the new LED bulbs in the passenger side - headlight and turn signal - and the incandescent bulbs in the driver side. Quite a difference! It will be a while until I'm driving at night. But I will report back full results here when I do. 3 Quote Link to comment Share on other sites More sharing options...
jft69z Posted February 29 Share Posted February 29 I'm literally doing the same thing in my car (just the headlights though). I'll be posting pics tomorrow as well. I have the Hella Halogens I got a few years ago though, then I got Philips LED replacement bulbs to use last week. I tried a bunch of the other LED replacement brands when I converted my truck a few weeks ago, and the Philips seemed to be better than the other ones I tried (a bunch of import ones, and also Sylvania LEDs from Amazon), plus the reviews on longevity and durability seemed more favorable. They weren't the cheapest, but weren't the most expensive either. Like you have found, night and day difference. 3 Quote Link to comment Share on other sites More sharing options...

B-Man Posted February 29 Author Share Posted February 29 Hmmm it's not them.. yeah weird, the link isn't working . I will pull up the part number off the box later and post it here. 1 Quote Link to comment Share on other sites More sharing options...
B-Man Posted February 29 Author Share Posted February 29 @jft69z, here is a picture of the part number label on the box. Quote Link to comment Share on other sites More sharing options...
B-Man Posted February 29 Author Share Posted February 29 I also bought new 1157 bulb sockets and will be installing them this weekend. One of the turn signal switch back bulbs was acting very funky. I went back and forth between passenger and driver side a few times and realized that the 50 year old sockets just aren't worth relying on, imagine that GLL Stradard 1157 LED Bulbs Socket Holder Auto Car Plastic Waterproof Turn Signal Tail Stop Rear Brake Light Base Harness Plugs Connectors Pre-wired Wiring Sockets https://a.co/d/4gEUM9B And I sort of said it earlier, but last summer I replaced the headlight bulbs, retaining rings, hardware and sockets. So this job was MUCH easier last night, not dealing with 50 year old screws, inserts, etc. it took me maybe 30 minutes to swap out both headlights and the turns signal bulbs - a quick job for sure. 1 Quote Link to comment Share on other sites More sharing options...
B-Man Posted March 9 Author Share Posted March 9 The 1157 bulb sockets above didn't fit. They have 4 plastic 'ears' vs the original having only 3 metal spring-ears. So I've ordered these: Standard Motor Products S55 Pigtail/Socket https://a.co/d/eVSyzyf Quote Link to comment Share on other sites More sharing options...
Tbo Posted March 13 Share Posted March 13 B-man Im having an issue with one of the parking lights staying Amber while the other is white. The turn signal for that light is also staying on. The hazards blink fine, but the switch back function isn’t. I replaced both flashers with led flashers. Quote Link to comment Share on other sites More sharing options...

Just a quick question to the group, since I had this issue on my blue oval......Are the flashers for the LED's polarity sensitive? Quote Link to comment Share on other sites More sharing options...
B-Man Posted March 13 Author Share Posted March 13 @DragCat all LEDs are polarity sensitive. They are electrical diodes, which are the equivalent of mechanical one way check valves. They can only be put into a DC circuit in one direction in order to function properly Note that with the 1157 type bulbs the little detents that stick out are at different longitudinal positions along the barrel. So they can only go in one way 3 Quote Link to comment Share on other sites More sharing options...

B-Man Posted March 14 Author Share Posted March 14 I just wired in the new, correct sockets - easy peasy. I mated the yellow wires on the new sockets to the blue original wires. Then brown to brown and black to black. The regular 1157 filament bulbs work properly with the headlights and turn signals. Interestingly, I'm getting some weird function with these switch back bulbs. One of them is very obviously not working properly. So maybe I got a bad set, or they are just of low quality. I'm going to return them (Amazon) and order a replacement set. Will see what happens. A little annoying for sure, but typical with these fancy new gadgety things, haha! 2 Quote Link to comment Share on other sites More sharing options...

Just saying, I ordered that laminated schematic awhile ago. Haven't had to use it but nice product. 1 Quote Link to comment Share on other sites More sharing options...
B-Man Posted March 15 Author Share Posted March 15 After returning the other set of 1157 switch back bulbs, I've now ordered these: PHINLION Super Bright White Amber Dual Color Switchback 1157 2057 2357 7528 LED Bulbs with Projector for Car Front Turn Signal Parking Lights https://a.co/d/a5Ae0t6 Admittedly, I do have a sneaky suspicion that something is up with the wiring for the turn signal on the passenger side. One of the original switchback bulbs is definitely bad. But there is some funkiness going on there when I swapped the bulbs between passenger and driver side. But the original incandescent bulbs work fine. We shall see once this next set comes in. Hopefully I don't have an electrical gremlin to troubleshoot!

B-Man Posted March 19 Author Share Posted March 19 So I've got this next set of switchback bulbs in. The passenger side is still acting very funky. As it was with the other set. So although I want to blame the bulbs there is sufficient statistical evidence to suggest something is up with the passenger side blinker circuit. Both turn signals work fine with regular incandescent bulbs. Weird. Any ideas what would cause one side of the circuit to have intermittent function with the switchback vs regular incandescent? There must be a weak point somewhere. Quote Link to comment Share on other sites More sharing options...
