LED bulbs in stock 996 housing

Has anyone tried the Lumen (or other brand), led replacement bulbs in the stock headlight or taillight housing? It seems like an affordable alternative, giving the reliability and brightness, but not the aesthetic look of the aftermarket complete assemblies. The only thing I can seem to find is the possible need for ballast resistors because of the low draw. Thanks, Paul

You can change the relay that will cover any LED's installed on your vehicle.

Could you please elaborate on this a little bit. I am looking to replace all the blinker, stop, parking lights etc with LEDs in the future. I was worried about the blinkers or stop lights giving me some kind of open circuit b/c the current draw is not enough. Any thoughts?

All quality higher end LED's nowadays have can-bus system built in so that you don't have to get a separate resistor and risk getting error codes. When it comes to blinkers, you may still have to get either a relay or additional external resistor to control the blinking speed.

You alluded to my next question about the CAN bus. I am gong to start a thread on that asking that question b/c in the search results i found no info for "can bus".

CAN BUS has nothing to do with your cars electrical loom that connects items such as headlights, tail lights, marker lights etc. CAN BUS is the fiber optic loom that connects the audio, DME/Motronic's,PSSM,security system, etc. Your car still has the normal copper based wiring system for electrical accessories. The newer 911's with factory LED's will already have an updated flasher. I have a 99C2 that I installed LED taillights, interior, marker lights, fog lights etc - all LED. I suffered from 'hyper flashing' on my turn signals as the LED's were not drawing enough volts. Instead of the 'old' method of fixing this such as installing a resistor across each circuit I installed an LED specific flasher relay that solved the problem. Google part#WM FLL301 The part is pretty cheap fix. The resistors that people used to install in the early days of conversion of lamp to LED taillights used to generate heat and IMHO were not an elegant nor safe modification. Most autos hops or speed shops will have them. Your interior lights don't normally need this fix as they have a constant voltage. The relay board is located up under the drivers dash past the fuze box. This is a shot of my relay and the location on the board.

"Can bus" or "error free" is the generic term that is often used to distinguish led's with built in resistors. I was not implying in anyway that these are related to fiber systems in any way. Although I do think the resistor in series to control blinking is crude. It has worked for me and several others all these years. Sorta like how Chevy has managed to stretch the push rod "LSx" series of motors all these years. Safety boils down to where you locate the resistor. Just like if you're the type to put a portable furnace next to some curtains.

except that CAN bus (Controller Area Network) is not a generic term at all. if people are using it as such then they should stop.

Thanks for the replies and info. Some of the manufacturers that I have looked at seem to offer resistors, but the inline type with scotch locks. I have considered replacing all the exterior bulbs with the same brand, but it seems like most people are buying the complete head and taillight assemblies.

Tell the sellers that. I was merely trying to help the OP look for names that he can look under to find the correct type of led's for his application. Do a search on eBay and see how many hits come up. It is a generic name in the automotive led world.

I read this thread and searched other but can't find an answer. Can I get H7 error free LED to replace my daylight/ running lights? This is for a 99 - 911 with halogen lights. I found these: http://www.ebay.com/itm/2-x-Green-50...282a58&vxp=mtr and then these: http://www.ebay.com/itm/H7-LED-Conve...7dec9c&vxp=mtr one is $22 the other like $199. I followed this thread and got those: https://rennlist.com/forums/996-foru...ight-lamp.html http://www.ebay.com/itm/Error-Free-W...602bb8&vxp=mtr but they are h6w. so completely useless.

mk1 mk2 bulbs are different daylight running light as in low beam? I wouldn't use led's for low beam....

yes low beam. can I put some kind of LED in there?

you can....but why? Maybe leds' have gotten better now but I don't think youll be able to see at night with led low beams....not bright enough

put LEDs in the fog lamps and use them for DRLs there is a hack that takes about 5 minutes and less than $10 to do do a search for it

See https://rennlist.com/forums/996-foru...l#post12800315 . I just posted how I installed one brand of H7 LED headlights for my low beams. They are MUCH brighter and have a pretty good beam pattern. Time will tell how reliable the setup is.
