Are you referring to the "front markers" as your turn signal lights? Let's keep it simple. The headlight unit consist of parking light, turn signal light, fog light, low beam, and high beam. I don't see why you would want the turn signal lights to be brighter but you can change those bulbs to LED if that helps. The term marker is usually refer to the side markers.
If you want DRL, you can try the mod below. It uses the fog lights as DRL.
