nstg8r Posted July 25, 2013 Share Posted July 25, 2013 I had previously done a similar mod but with front turn signal LEDs converted to parking light/turn signals. Unfortunately, I never did a write-up with pics, so here's one with my rear turn signal LEDs converted into turn signals/back-up lights. (7440 socket converted to 7443 socket) Parts needed are 7443 Switchback Amber/White LEDs; 7443 pigtail sockets (standard, not CK); 7440 bulb base with pigtail connectors; your choice of connectors, solder, wire taps, etc. I purchased everything from Autolumination.com. Sockets and bulb bases: The 7443 socket needs a small modification to fit into the lens housing. There's 2 small tabs and two large tabs on the socket. It's the two small ones (circled) that get removed: You can connect your sockets and bulb bases however you like. I used butt connectors. The green (ground) wire from the 7443 socket gets attached to the black base wire. The white (hi circuit) wire gets attached to the red base wire. The red (lo circuit) wire will get tapped into the +12V wire from the oem back-up light connector: The way the switchback LEDs work, the hi circuit powers the amber LEDs, the lo circuit powers the white LEDs: Stock wiring harness with everything connected: Results (passenger side with mod): I didn't take a pic of the turn signals, but they operate as expected. The particular LEDs I purchased will turn off the white LEDs when the amber LEDs are activated, so if I'm in reverse and my turn signal or hazards are on, the white led back-up light part of the bulb is deactivated.

BadTrainDriver Posted July 25, 2013 Share Posted July 25, 2013 Nice write up...but if I may make a suggestion, there is a company called Posi-Lock that makes much better wire connectors than what you using. They aren't cheap, but you'll never have a problem with them! http://www.posi-lock.com/posiplug.html Link to comment Share on other sites More sharing options...

They aren't cheap, but you'll never have a problem with them! http://www.posi-lock.com/posiplug.html Normally I would solder the connections or use waterproof connectors, but since this is in an area that shouldn't get wet, I just used what I had lying around. For wire tapping, I always use 3M Scotchlok moisture-resistant insulated tap connectors. Link to comment Share on other sites More sharing options...

marsho Posted May 18, 2015 Share Posted May 18, 2015 I know this is an old thread but my question is warranted. Did the switchbacks give your turn signals "fast-blink"? or did you previously have the little module that prevents it installed? I had switchbacks on my 09 WRX and had to install the module that prevents the "fast-blink", but seeing as this is a different application I was wondering if the situation still occurs.

I had the TapTurn II module installed, so that prevented it. Also, I upgraded the switchback bulb to the V3 Tritons from VLEDs that have a built in resistor which also prevents the hyperflash. Without either of those, yes you would get the hyperflash. Link to comment Share on other sites More sharing options...
