Tail Light Power Requirements for LEDs

Have an F430 F1 that I want to upgrade its tail lights to LED based. I have read in some places, which I can't seem to find again, that the car measures the power to the tail lights to determine if they are working, which I also understand can effect the F1 transmission operation. Is this true? And if so, anyone have any idea how close the power measurements are? Reason I ask is the LED lights I am looking at would replace the 5W/12W dual filament bulbs with one that use 4W/8W. Any idea if this will cause me any issues? Thanks much.

 

Thanks guys. It is the HIDRUS units that I am looking to install. Sounds like they will work, so that's good news. I'm not familiar with the Facebook group you refer to. Can you provide a link to the thread? Thanks.

 

I purchased the F430 set from HDISRUS and installed them, but ended up returning them. If you check the outside dual-filament style LEDs they supply, you will find that the light output difference from when the headlights/parking lights are on to stepping on the brake is very minimal. At night I can easily see getting rear-ended as the brake light is a barely noticeable change from the parking light. Has no one else had this issue with this product? Additionally, one of the single filament units was defective on delivery - doesn't give me a warm quality feeling.

As per my original post: Does anyone know what the F430 computer is actually looking for to determine the light is OK and not throw F1 problems? Is it looking for a minimum amount of current draw, and if so any way to find out what that is? Thanks much.
