I got these switchback DRL's about a month ago as a gift, and finally got the time to put the lights and resistors in today.

http://www.corvettemods.com/Corvette...Ls_p_5535.html

Pretty sure I installed the resistors correctly (red to blue/white wire, black to black) on the far outside wires for the DRL's, and after the install this is what I have going on: when the car is on, no lights are on. When I turn on the parking lights, both light up white. When I use the blinkers like this or with the parking lights off or with the headlights on, only the left blinker is working, the right one does not work at all. The right one was working as a blinker when I just plugged in the bulb and tried using the blinker to be sure before I put it back together, but then after it didn't work at all. Also, the other amber light next to the DRL's on the right side is no longer lighting up, and I pulled it out and it is definitely not burnt out. I'm really lost and have no idea why the lights are not working correctly, thank you in advance for any help.

 

Bump...any help is appreciated, can't drive my car without blinkers

 

They sound defective to me. That's not how they should work.

 

Does it have anything at all to do with the resistors i wired in? Or is the way they're functioning totally dependent on the actual led bulbs?

 

I would pull the resistors and try w/ out them.

 

Did you ever resolve this problem? I just ordered switchbacks and resistors.

 

The Switchback LED from Corvette Mod's




LED Switchback


Got a similar problem with the Switchbacks ( the same ones from Corvette Mods.)
Parking lights come on only amber instead of white , no blinkers.
I don't need the resistors , have the relay harness installed , works great on the rear LEDS with sequential switches and as well on and sidelights
Changing the led bulb 180 ° in the socket gives only amber light with parking lights on , no blinker either.
Have to check fuse # 2 in underhood fuse box today
Exchanging mini relay #38 <--> #40 in internal fuse box didn't make any difference.
Will measure the different voltages in the socket today and put the Switchback LED on the test bench.

Read something weird on Ebay a while ago from a (Chinese) seller for similar switchback LEDs who exchanged the wiring in the sockets.

I will let you know as soon as I have them operational.

This is what I got for now from the LED's themselves and I check back later with the (CHANGED) wiring from the Vette.

 

The wiring in that diagram you posted is called "CK socket" and that isn't the wiring used on the C5. I believe it's more popular on European cars. I'm not sure if the C5 wiring is called a special term but it's usually just referred to as the standard 3157 wiring.

The C5 has both grounds at one end of the socket. When you reverse the bulb it connects the signal and running lights together.

 

Nice of you to state your knowledge like this, when you believe or not even sure.
I only state something when I'm 100% sure.

This is from backside of the LED ONLY !!
There is no wiring to go with it yet.

I wasn't ready, just trying to be helpful.
Wanted to make some pic's.... well, dunno.
Maybe YOU make the pictures then ?

 

This is what I got after measuring the voltage at the socket
Without major changes to the Lamp Socket Wedges Part # 12160394 the Switchback LED's cannot work.
Working on the RF side to change the socket wedge and the wiring.

 

I'm not sure what you're rambling on about. Maybe you have a hard time comprehending a written sentence. I'm 100% certain the socket layout to work with that switchback picture you posted is referred to as CK and I'm also 100 certain it's the WRONG switchback light for a C5.

I'm not certain what cars make the CK wiring popular but that doesn't really matter when the C5 is the car of interest. By wiring I was referring to the way the socket was wired or the way that bulb type gets wired.

But go ahead and keep investigating without bothering to use Google to look up the term I gave you but instead blindly trying to figure what's wrong with your car or how to make those bulbs work. Funny how I both told you it was the wrong type and that the C5 had the grounds at the same end and then you post a rude response before posting exactly what I told you as if you came up with it. Why'd you even post when you are going to ignore the responses?

Why would I bother to make any pictures? A Google Image search of "3157 CK socket" or "3157 socket" will give dozens of pictures showing the standard and CK socket wiring. No need to re-invent the wheel. No need to investigate myself. I already know the 2 possibilities and already know the one you posted is useless for a C5. That's why I told you it was wrong.

Also, it's just a socket, not a socket wedge. I suppose you could call it a wedge bulb socket too.

Send those switchbacks back. They should eat any costs involved being a Corvette specialist yet supplying you with the wrong bulb type. Unless you didn't actually buy the bulbs from Corvette Mods.....

 

That is what I said as well , with an explanation why.

See:
Corvette 2003 Service Manual Book 3A of 3 , GMP/03-Y-3
Page 8-238, 8-239 Lighting Systems (Body and Accessories )

Park/Turn Signal Lamp - LF (Domestic) or RF (Domestic)
Connector part information
* 12160394
* 3-Way Lamp Socket Wedge, Base W3 Right Angle (NAT)

I'm just arguing and rambling.

And why would I bother to yap here about $49.99 + $ 27,00 Transport + $17,00 Duties I paid for the darn Led's,
I know now who can be trusted and who NOT.

Sir , you're fully right, I won't say or type a word anymore in this forum.

 

Have you confirmed the Switchbacks only take power the way you drew them? You listed on your drawing that they still work the same way when turned 180* which indicates they may be a smarter built bulb than the typical ones.

Referring to your drawing, the negatives on the right side in your drawing can't be joined or you couldn't reverse it and still make it work the same. Try putting positive on the top right and negative on the bottom left and see if it works. If it does, then try positive on the top left and negative on the bottom right. If both tests work then that bulb should work in the C5 socket.

I'm doubtful because they are typically made for only one of the wiring schemes, but it's possible to build a LED bulb that is universal.

 

You do realize you are posting to a 3 year old thread, don't you?

 

Your not going to respond anyway so here goes nothing... Your avatar may hit close to home? Lionelhutz is a very bright, very helpful, valued forum tech... he knows electrical and you should LISTEN to him...he was trying to help you and you disrespected him... If I were him I would put you on the DO NOT HELP list... unless of course you apologize and try to actually learn something...
Maybe should have come to the forum FIRST and asked some questions about what will work...or won't. Maybe they'll take the ones you ordered back.

 

They don't have to take them back.
I made them work !

Modified the '3-Way Lamp Socket Wedge, Base W3 Right Angle (NAT)' part #12160394.

Now they always fit for these switchback LED's , it's even possible now to put in the ordinary bulbs back in.
That was my plan all the way.
And wanted even to made some DWG's with pic's and/or a video for all C5 owners who want LED's all around.

That's what WE do when we're abroad, we have to make things work.

 

Yes, because nobody fixed it.

 

I did fix it.

Opened the socket

I removed one earth pole from the socket.

exchanged the Black and Brown wire in the socket

What I get is :

Engine ON

DRL = Orange permanent ON
Direction = Orange ON/OFF flashing

Engine ON/OFF

Parking Light ON = White ON Orange OFF
Direction ON = White OFF , Orange ON/OFF flashing ,
Direction OFF > 750 milli sec = Back to White


Headlights same function as Parking lights.

Warning flashers = Orange ON/OFF

Made some pic's and dwg's

Anybody wants them ?

I,m just a sparky with experience , just don't call me names.

 

I'd love a copy of the dwgs or pics if you are willing to share. I just ordered some switchbacks and am anticipating problems with my C6. Thanks!

 

Hey Greg ,

Of course , just give me a 2 days , I'm at another location.
Gotta pull it from another PC.
