As for my underbody neons, i mounted them to the running boards (a little below the bottom of the explorer), thus i have achieved such a good glow. Some people who have their neons mounted on explorers, do not have running boards, therefore they are forced to stuff them high up under the frame, and alot of glow is lost. My neons are mounted below the frame, so all the neons glow is used.
For the two strobes in my center front vents...what i did, was unscrew the entire radio/ac/heat/vent front face. I pulled it out, and then the vent is exposed. You will see, that when the face of the radio thingy is taken off, that there are some holes running from the glove compartment to the radio. Thus, i pulled down the glove compartment (like, i disconnected it - when you pull out the glove compartment, it gets jammed on something so it will not dump everything on the ground...i did it so that i made it do this (dump everything on the ground) This way, i was able to mount the transformer for the stroebs in a space behind the glove compartment, and run the two strobes up to the vents.
Those are only temporary. Within a week, im gonna be ordering a set of purple, a set of green, and one purple and one green headlight neon.
Im going to put the green headlight neons in my front passanger side vent, and the right vent of the front center console, and the left vent of the back vents.
For the purple, im going to put them in the drivers side vent, the left front center vent, and the back right vent. Should look sweet!
As for making your neons brighter...technically what you say should be correct. Over at the SG message board...we had a disscussion of this awhile back. Some people have use foil, or other metalic substances to bounce the neon light back to the ground. Most say it actually does increase the brightness.
However, a couple people said screw that and have installed numerous underbody kits...i probably won't have to do that, cause their trying to achieve the glow that i have....and i only have one underbody kit!!!
Im glad other people have neons on their explorers...dosen't make me feel so much like a loser..... Im the only kid at my school with 3+ neons...and like the only kid in my town with underbody neons...but hey, im unique!!! haha
