Long story short I am getting rid of my LED bulbs for $75.00. I paid $159 for them 3 months ago, but they have been used so I am slashing it to 50% off. They are a pair of lasfit plus 9006 LED's. They work great, but the computer system on a 2001 Z06 does not like these at all, not to mention the beam pattern is way off with OEM reflector headlights. They would work for any car that uses 9006's. Eventhough I like these and they work well giving off plenty of projected light in the 6000K range. I am switching back to halogens. I am thinking about buying a set of OSRAM Nightbreaker 200's if they will fit. I have noticed when I installed LED's in my car. that the computer system randomly brings up TCS failure or service traction control system at random. The lower voltage from the LED's does some crazy things to the computer system on a 2001 Z06. When I had halogens these random voltage things being thrown up were never an issue. I have had the entire traction control system looked over and everything is snapped in tight.No damage to the wiring and no failing devices during diagnostics.

I also found my parasitic voltage drain I spoke about years ago. It wasn't the battery and it wasn't the alternator as I had the big 3 install done for more power efficiency. It was leaving a cell phone charger plugged in inside the center console of the C5 Z06. The cigarette lighter aswell as the center console charger port never shut off if something is left in it even if a cell phone isn't plugged into it. It will drain the power system down very low, which causes very rough starts and low power starts on the vehicles initial startup. Added to the fact LED's can make the TCS service traction control system error pop up. This is just a heads up for people using that charging port inside the center console for stuff.

I've had sylvania silverstar ultra bulbs before and while I could see farther down the road the light up close seemed way dimmer than the original OEM bulbs were to the road closest to the vehicle. I could see very far up the road, but not much visibility upclose within the first 25-50 feet. I guess the wider the beam pattern, the less light being projected directly infront of the vehicle up close. When it was raining at night with silverstar ultra's installed I could barely see the road itself, but I could see very well farther down the road, just not upclose to the vehicle. It sounds weird, but it's like it was dimmer upclose to the vehicle.

If the OSRAM Nightbreaker 200's are not an option for a 2001 Z06 corvette what halogen bulbs would you suggest. Not for style, but for overall visiblity both upclose and far away. I don't want LED's or HID's at all. My cars computer hates these. Not to mention they are not meant for reflector based headlights. They produce a weird beam pattern. I once spent $600.00 on a top of the line quality HID kit 6000K. The end result was hours of time wasted trying to fix this canbus issue with resistors. The lights would constantly flash even with additional resistors installed and the bulbs themselves would make the plastic cover in the reflectors extremely hot. For this reason I am looking for halogen's only. Too many unnecessary issues plus random computer errors with LED's installed. Not looking to change out headlights to projectors. Looking for the best halogen bulbs possible for a good mix of upclose and far away visibility combined.

Based upon what I have read from various sources. The bluer the headlight bulb is, the less overall light it produces. Blue light scatters more making it harder on your eyes.
