My nephew is a huge NY Yankees fan. So, I made him this lamp. It has two settings (and a third that combines the two). One lights up the ball blue and the other sends up a NY bat signal onto the ceiling.
I used a blue led light for the main body of the ball and a white led for the bat signal. I bought them here: https://smile.amazon.com/gp/product/B00H98OS2W/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1
There is a hexagonal hole for the switch which will fit the three terminal switch found here: https://smile.amazon.com/Gardner-Bender-GSW-62-Electrical-Terminal/dp/B000HEKSB0/ref=pd_bxgy_60_img_3/137-7911674-4029762?linkCode=w61&imprToken=7Zdc9Vq0-iCCO.CevOe5jA&slotNum=2&_encoding=UTF8&pd_rd_i=B000HEKSB0&pd_rd_r=411ad33d-64c6-11e9-8c99-472c1499fd9d&pd_rd_w=EP4Bs&pd_rd_wg=liuMN&pf_rd_p=a2006322-0bc0-4db9-a08e-d168c18ce6f0&pf_rd_r=1RT4F805VHAD5EA2SV63&refRID=1RT4F805VHAD5EA2SV63&th=1&tag=tv-auto-20
