The Xenons, or HIDs, are approx 3 times brighter than the halogen version, if you choose to go with the 4800K...
The halogens are still at least 35-40% brighter than our stock lights due to the superior projector optics. As far as the turn signal, it is not affected at all.
I've been asked if the headlights will be different in design. To answer your question, the Halogen and Xenon versions are identical to each other, with the Xenons having a slightly deeper projector. However, on the outside, there will be no differences.
