Default Re: Are These the Correct LEDs?

This is exactly what I used in my car - they work great and are a huge improvement over the stock lighting pattern/output. I have no regrets whatsoever.

However, be aware of the following:
- The stock sheet metal buckets need to be slightly modified to allow these to fit. Specifically, there is a small "bump" on one side of each bucket, that needs to be trimmed away for these to fit. I used a Dremel tool with a cutting disk and simply cut off the sheet metal in that area. That worked fine and there is plenty of material around the cut to provide strength.
- You will need to modify the foglamp wiring to ensure that the foglamps work. I was not able to make load resistors work with these LEDs. I did the "Yun mod" on the foglamp relay and that worked out perfectly.
- The LED units are quite a bit heavier than the stock plastic headlamps. My headlamp motors (specifically the plastic pellets inside) were already on their last legs and pretty much gave up after I made this mod. Replaced the pellets and all is well again.

Finally, be aware that this unit is available in a black background (as pictured) and also in chrome. I chose chrome as I think it looks better / closer to stock. YMMV.

Ditto... if you know what that means.

I put them in 3 different cars they fit right in no mods.

Hmmmm... That makes no sense to me at all. Controlling the fog lights is a relay. To operate the relay one side of the relay (actuator) coil has to be @/near ground potential, either by physically running one side of the relay coil to ground OR replacing the normal resistance path to ground via the "load resistor".

These two methods have different results:

The LOAD RESISTOR method restores the OE function of the fog lights - i.e., they turn OFF when the high beams are activated and turn ON when the lo beams are activated (assuming the fog light control switch too is in the ON position in the first place).

The other ("Yun") method physically interdicts the relay circuit and instead physically running one side of the relay coil directly to ground. This method assures the fog lights are ON regardless of the (hi/lo) bean status of the headlights, assuming the dash fog light switch is selected to ON, of course.

Indeed, I understand how the system is supposed to work.

My issue was NOT that the fog lamps did not turn on or off as they were supposed to. The problem was that turning on the foglamp switch, regardless of the position of the headlamp switch, also turned on the high beam LEDs. This behavior occurred with or without the load resistors.

If you examine the rest of the circuit diagram, you see how the foglamp relay normally grounds through the high beam filaments. I have no idea why this does not turn on the normal high beam lamps; presumably something due to the voltage drop required. Perhaps the LED "high beam filaments" (in quotations, I know they are not filaments per se) need less of a voltage drop to turn on.

Also it is entirely possible that different LED headlamp units behave differently in this regard. And perhaps this behavior is specific to the load resistors employed.

In summary, as I have posted elsewhere, you can either use a combination of LED headlamps and load resistors that have been shown to work by someone else, OR you can do the Yun mod and be assured that everything will work, but at the expense of the foglamps not turning off automatically with the high beams.

Default Re: Are These the Correct LEDs?

I tried those briefly but wasn't super impressed with the light output. I'm running the Genessi 7x6 and I'm really happy with them, they are closer to $200 for the pair though. And yes the Jeep XJ and Corvette are the same, I own those exact two cars lol

Thanks everyone... They'll be here Friday. I hate driving my Z at night.... and the wife forget it... she is white knuckling it the whole ride... I figure for $85.00 they're worth a shot over the yellow stockers.

Robert,
Do you know the model number of the Genessi 7"X6".
