I have a 2011 IPL coupe . 2 of my individual LED tail lights burnt out. Tried googling it but no luck. Anyone here know what bulb size it is ?

 

The LED's are- technically- not user serviceable. Unless you have extensive soldering skills it is much easier to either leave the tail light alone or find a replacement. For two LED's I'd likely leave it be, for now.

This thread has some good, detailed information regarding how to crack open the tail lights and "tinker" with what's inside.

 

@ILM-NC G37S - related but weird question that of all people here you might randomly know LOL. Do you know how much current the OEM tails draw when on full bright (IE brake lights?)

 

@rotarymike Actually, I have no idea but being that I will be working in that area (on my rear fog lamp project (whenever the switch from the UK gets here)) I will find out.

Being the brake lights are LED's which are rated in mA (milliamps), I would estimate the whole BRAKE LAMP circuit- including the middle "3rd brake lamp"- to be at or less than 1-1.25amps. The whole circuit is fed off a 10amp fuse so definitely not a high current draw. Maybe one of our LED suppliers like @Diode Dynamics would have a better estimate?

I'll update in the coming weeks unless the weather gets too hot/humid/miserable to do any wrenching...

 

Thanks - I thought you might have metered them already LOL with all the stuff you've done. If you can't get to it, no worries, I can throw my meter on it someday, I just do not have a lot of time on/in/with the car these days.

I'm planning on deactivating the outer running light (only) so when light on - inner ring, brakes on - both rings. To do that I'll need a NPN of the appropriate wattage...

 

FYI I'm 99% sure you need to open the taillight for it. I too hate this light. Ruins the look in my opinion.

 

100% sure. Have some JY tails so I don’t mess mine up lol.

 

Added: I like the look - traditional 2 round light on each side like prior generations of the skyline. But it is a little dated, yes. And for some reason people cannot see a black car with bright red lights slowing down in front of them, and the accelerometer-based taillight flasher is no longer being made, so...

 

Looks like the Infiniti tails use Agilent HPWx Superflux LEDs.

The nominal drive current is 70mA per LED. So, count how many individual LEDs you see, x 0.07 will give you an approximate current of each tail.
