Philips Ultinon D4R Xenon bulbs conversion

[Teks0427]

Hi guys!

May pair ako ng Philips Ultinon D4R xenon bulbs.  I wanna know kung pwede syang gamitin using a generic (China made) ballast na pang D2S/D2R na bulbs.  Kung hindi, ibebenta ko na lang siguro...   

What's the difference between D2R and D4S anyway?

Thanks a lot!

You cant use D4R/S bulbs with D2S/R ballasts. The bulbs wont fire up. Mercury free ang D4S/R
