Hello again!

Apparently I am not satisfied with the response time of the D1S HIDs in the low-beam projectors of my '09 Superb MkII. Now I see all these D1S LED conversion kits online and an urge to try them out. However, I am not sure if the plug-and-play LEDs will light up or just explode as the ballast creates a very high voltage to start-up the HID lamps. Could anyone kindly shed some 'light' on this doubt?

Thanks and regards

When you say response times, do you mean their time to illuminate from off to full brightness? Xenon bulbs usually take a few seconds to warm up and reach their optimum light output.

 

If the current D1S bulbs are the originals (and therefore 10 years old), you might find a new set will improve things?

 

LED bulbs seem to perform much better behind projector lenses, but given how sensitive the BCM / CECM can be on these cars I'd be tempted not to bother.

Hey, thanks for the response. I changed to new RCP 6000k D1S pair about 3 months back and while they seem good enough, I just need some more low beam illumination without losing the slight hint of blue. Besides, a friend of mine also wants to upgrade his factory HIDs ('12 Octavia II L&K) to LEDs, so I got curious as well. Most plug and play bulbs don't even have the D1S mount. Yes, you are absolutely right about BCM taking the load. I wonder if they are adapters for voltage balancing. Do the D1S have a built-in ballast?

A quality xenon will give you more light in a xenon projector than a drop in LED conversion.

 

A D1S has a built in igniter but the ballast is separate.

Try a lower Kelvin bulb. Light penetration drops over over 4500k. Try something in the 4000k mark and it should provide better light output. 

 

Or upgrade the ballasts and fit 50w xenon's.

This will lose the ‘slight hint of blue’ though (no bad thing IMO, but not what the OP wants.

Had the OEM Philips Xenstart 4300K before. Did not like it at all. I have 6000K H8 LEDs running in the fog lights. The color projected is somewhat in-between the 6000K HIDs and OEM 4300K. Also, wouldn't mind upgrading the high-beam H3 halogens to LEDs as well.

All issues sorted. Got Plug and Play D1S LED pair (6500k) from aliexpress and switched the halogen high beams to H3 Philips. Visibility has improved tenfold
