The DDM LED emitters look narrow enough, but like all LEDS the heat sink in between takes up space so they are still 1-2 mm away from the center line.
I like
these
as the LEDs are small, seem close to the center, are covered so nothing can damage the emitters and have fanless heat sinks.
My lamp housings don't have a back cover. The engine bay is covered under so not much dirt or moisture finds its way in.
In fact I just ordered them, for the hell of it
I just want to see what they are like, if they are any better than my cheapos or not.
If they really are much better they might replace my HIDs. Then I may buy their H4 counterparts for my wife's car. But they need to be reliable - replacing the lights in a I10 means dismounting the lamp housings themselves...
