Jason MacKenzie 3 Posted April 26, 2014 Share Posted April 26, 2014 has anyone had any success with any front turn light LED conversions? switchback or not! I just tried a set of LED switchback lights and load converters with no success! turns out it has something to do with the cars "body control module" and how the blink is controlled not from the bulb itself but from the module. I have a 2013 1LT any ideas would be greatly appreciated. Thanks Link to post Share on other sites
Roberto.salvador92 3 Posted July 10, 2016 Share Posted July 10, 2016 I haven't tried it yet. Which ones did you order? Where the load converters built-in or attached? I'm also trying to look into LED headlights by http://www.carid.com/2013-chevy-spark-led-lights/lumen-led-headlight-conversion-kit-88855853.html But not sure Link to post Share on other sites
Roberto.salvador92 3 Posted July 10, 2016 Share Posted July 10, 2016 Also were they CanBus compatible? Link to post Share on other sites

Duncan 5 Posted October 9, 2016 Share Posted October 9, 2016 Is the turn signal flasher actually replaceable on our cars? Before investing in a bunch of LED bulbs, I decided to find out for sure. Ideally, you'd be able to just plug CanBus-compatible LED bulbs in and "fake" the computer into believing that all the bulbs are incandescent, but I've heard and read that this alone doesn't do the trick. So the next options are to wire in some resistors (I'm not a fan of this personally) or plug in a new flasher relay that will accommodate LED circuits without a problem. Since I'm inclined to go the flasher route, I looked that part up. Advance Auto and RockAuto both list the Tridon/Novita EP35 flasher unit as a standard part for our car, and note that it is LED compatible (it even says so on the part itself). Good enough, right? However...a quick application search of Novita's own site (link) seems to contradict this supposed compatibility, advising that flasher replacement is not possible and noting that our cars use a Body Control Module (BCM) that controls turn signal activity internally. So...huh? After a little more research in the 2014 owner's manual (free PDF from Chevy; pages 10-30 to 10-35 detail the fuses and relays all over the car), it appears that there are actually eight (8) relays in the interior fuse box being referred to as BCMs. No indication is given as to which BCM controls what functions, but I assume that one of them controls the flashers. To be honest, I haven't looked inside the fuse box since we got the Spark a year ago - I hadn't really had a reason, but I got curious today about what it would take to get brighter LED signals and brake lights working before winter hits. I'll take a deeper look in the morning and see what I can find. Duncan Link to post Share on other sites
Ray Dockrey 97 Posted October 10, 2016 Share Posted October 10, 2016 The flasher is built into one of the BCM's and is not replaceable. A lot of cars are going to this method. The click you hear when the turn signal is on is coming from the car speaker and not the actual flasher. Retired old Gearhead 1 Link to post Share on other sites
Duncan 5 Posted April 18, 2017 Share Posted April 18, 2017 (edited) Which is what I figured out, unfortunately. So, my thought now is that maybe I'll replace everything but the front amber bulbs (to maintain electrical load and keep the flashers from going so fast). That will at least give me the brighter LED glow at the back of the car, which has been my main concern. And honestly, the backup lights are already way bright enough - I can't imagine what the LED version of that would look like. But I'm willing to try, of course.

Eric1984 16 Posted July 10, 2017 Share Posted July 10, 2017 (edited) I did the front switchback LEDs for the turn signal recently, here is the link to my thread http://chevysparkforum.com/topic/4887-switchback-leds/ On 4/18/2017 at 3:55 PM, Duncan said: And honestly, the backup lights are already way bright enough - I can't imagine what the LED version of that would look like. But I'm willing to try, of course. I also have LED's in my reverse lights and they are very bright, got them at superbrightleds.com. As well as LED's in my map light, trunk light, and brake lights.
