Currently have the Morimoto retroquik kit on my 993 and while it's great when it works it's too finicky. Bad ballasts, bad igniters etc. Has anyone used Carnewal's LED bulb below with the morimoto projectors?

I'm also wondering about these H1 LED bulbs from Carnewal. I currently run some H1 LED's which were cheap on Amazon and I'm pretty disappointed with the illumination. I know that LED's don't project the correct beam pattern to align with our halogen headlamps, but Carnewal says his produce a perfect beam pattern in our halogens.

 

How would these be wired up, as I see only a single connector. I thought the OEM bulbs had two connections.

 

H1 LEDs from Carnewal. Recommended!

 

H Curated,
The High Intensity Discharge (HID) xenon bulbs are only finicky if there is a ground fault due to dirt on the bulb envelope or a ground leak on the high voltage wire or the bulbs are new and need a bit of a burn in period..

See the gotchas on this page; it may help sort out your intermittent issue:

The hid setup is finicky because the morimoto ballasts and igniters keep going bad. New ballasts and igniters solves the issue but I need a system that I can reliably trust to always light up. The Morimoto and Tore kits while great when working are just not reliable.

 

Hi Curated,
I use the generic thin ballasts from eBay. They can be defective but once they prove to light up they seem reliable.
Do you have moisture or other issues with the headlight pods that may influence reliability?

No moisture or other issues. Just failed Morimoto ballasts. Can you post exactly which thin ballasts you use and have been trouble free?

 

Here are ballasts:

Here are complete kits:

I suspect they all come from one or two manufacturers in China. My kit is about 15 years old so its branding is not relevant.

If you examine the ballasts you have had failure problems with, you may be able to determine which products to avoid.

Since the complete kits are inexpensive, you may want to consider wholesale replacement and avoid any plug compatibility issues.

Keep in mind that the slim ballast will allow you to fit all the components inside the headlight pod housing.

The key is to bench test the kit and burn it in a little before installing it in your car.

Hi have Tore’s low beam HID for about 6 years no problems at all, 35watt, 4300K. For the high beams I went to Amazon, in 2022 I ordered Fahren H1 LED units they are 6000K 1000 lumen 60 watt. These have ballasts and are fan cooled, they work well, super bright, but the light control is not precise so a huge area is illuminated not good in rain or mist. Two friends bought LED without ballasts or heat sink/fans and they overheated after a few minutes, one melted the plastic of the headlight unit the other just died. The bases also need a heat isolator, most have a silicone rubber ring that adapts the universal bulb to the H-1 diameter, this allows the fan to cool without heat transfer to the headlight bucket.

 

Can vouch that these work well and are an easy swap. No ballast to deal with and much better than halogens.

 

Funny, I had some Bergville LED bulbs and had trouble with flickering, switched to the Morimoto xenon and have had no problems. Since then I've improved some sketchy ground connections and have better, flatter, higher voltage in my whole electrical system, so the LEDs might work better now, but I switched bulbs before I did that work, and the xenon bulbs / ballasts just worked better.
