sounds like an impedance mismatch.... the abs/psm is triggered when it thinks you have a blown brake bulb.

 

whats up guys? i installed my tail lights today and they look out of this world!!!! no Hyperblink no nothing. my car is a 1999 with litronics that didnt come with the car. i put them in my self. they look so good! only one question? when you open you fog lights for the rear arent both of them supposed to light up? mine only ones does??

 

Because the new LEDs in the new 996 tail-lights do not consume as much power as standard bulbs, they do not draw an equal amount of current as standard bulbs. This lowered current draw causes the car's computer to "think" the bulb is burned-out, which triggers a "hyper-flash" mode designed to notify the driver a bulb replacement is needed.

To trick the car's computer you will need high wattage resistors 20-50 watts. NOTE: Do not use the small, low wattage electronic resistors as they will be overloaded and possibly melt.

To fix your Turn Signal Flashing problem: To start, you will need 2 Resistors. The resistor's values depend on how many led bulbs are used to replace each idvidual bulb. For example, if you only installed 2 bulbs (see pic below - each bulb consists of multiple, small LEDs) one bulb per tail-light on each side, then you would need (2) 6-8ohm resistors between 20-50watts. Note: I do not yet have a set of the new 996 tail-lights to test the the LED's current draw for each location. Regardless, this information should remain applicable and fix the hyper-flash issue.

The brake lights are not working correctly and/or the PSM/Brake dash light is illuminated: The PSM & Brake in-dash, indicator lights are inter-related. Once the following process is complete, these lights should turn-off as your computer will no longer have a reason to trigger them on. You will likely need to complete the same resistor mod. However, you may want to use a slightly higher wattage resistor, because the brake lights have a semi-continous current draw versus interval flashing.

Here is a general use diagram to follow for installing your resistors:

 

Glad to hear they work for you. Rear fog light only illuminates on driver's side. Been that way a long time.

 

jstrat85..can you please post a pic of the tail lights without putting them on or pushing on the brake. I would like to see what they look like. Thanks for the help..very much appreciated!!!!

 

i thought that too. thanks i will post pics asap but my photobucket account is being gay!

 

will do buddy.

 

Post 56 in this thread shows pictures. Post 80 in this thread refers you to original thread with lots of pictures. Can't do all the work for you.

 

I think, Paul wants to see clear-red combination on the car, which photos I would also like to see

I have done it in my 996 and looks great.

Just add a bulb to the other side,

in my case , i wired it to the existing 12+ once lights are on, therefore bypassing fog switch. i used LED bulbs so they are not super bright.

 

Installed my lights today they look great no problems at all with hyperblinking or lights on the dash coming up. I got the black/smoke my car is a 99 C2CAB with aftermarket HID'S in headlights and fog lights. Will post some pics later took some daytime pics going to wait till it gets dark out to take some more.

 

i insatlled a bulb in there but it still doesnt work?

 

some pics of red and clear on my car. will post more pics later.

 

Looks amazing

 

You have to wire it to the other fog light.
