The light output of the taillights, third brake light, and mirror lights are all much brighter than stock light outputs. Recon's headlights when using standard halogen bulbs have slightly more output than stock, but if you're looking to significantly increase output, you'd need HIDs or LED replacement headlight bulbs. Just keep in mind that Recon's headlights use a 9006 bulb for the Low Beams and an H1 bulb for the High Beams.
