Do you guys think the prices of the philips D4S bulbs will keep going down or are we at the point that they are pretty much commodity priced by now?

 

My feeling is that they aren't going to go down much until demand drops. That probably won't occur until we see new LED technology (adaptive cut-off, topographic control) close the gap between xenon and LED headlight capability. From what I've read ... 3-4 years.

So ... the D4S will probably come down sharply in a few years, just when you won't want them anymore.

 

i think prices are flattening. it will continue to steady head down (just nature of technology) but i don't think it would be dramatic
