thanks everyone, yes it's an enclosed lightbox.
Had to drag out a controller and try it out, looks awesome in the dark.
Not sure what I was thinking making it so big, last years was too short, so I got carried away. Hope it will withstand the wind, prob have to have some support wires or something. I have 5 gallon buckets I'm going to fill with cement and set the 4x4 to hold the top up. We'll see!
I was wondering what material you are using behind the letter cut outs. Thanks again!
I make vinyl stickers, so I use the vinyl material, tried purple first but was too dark for light to get through, so I ordered some orange and it works great. I hot glued it sticky side in for fear of collecting a ton of bugs and crap.
Now I'm going to make a Tune in lightbox, thinking a tombstone shaped sign.
If you need to know where to order pm me, it's about 13 buck for 10 yards and another 12 or so shipping, might try ebay for smaller amounts.
