Im about to purchase a SGgold series undercar neon kit, and im stuck between neo-blue and white...
I have a steel grey2004 Mazda 6i Sport..

and also are there any other undercar neons that are just as good as street glow out there??

 

led light are better than neon they last longer and dont break as fast as neon lights ...go with the blue

 

well i would like to get the brightest outthere alsoand i heard LED's are not as bright as the gold series neons

and also how is the OPTX neon seriesby street glow (better or worse than gold series)??

 

i went with the Underglow kit.
and if you get the high-end model, you can make the led's do watever you want.

i bought the middle end kit. so it will do 1000 colours, pulse, and strobe.

honeslty, just go with LED's. they are more brighter, and they will last way longer. plus the require very very little power, so you can keep the on when the car is off, and it wont drain the battery
