Step 2: Making it Fit
1.Pull the light out of the socket that you are going to put the twinkling bulb in
2.There will be two wires on the bottum of the housing of the bulb- bend them so they are straight
3.Pull the bulb out of the housing
4.Do the same to the random twinkling bulb
You should now have 2 light bulbs and 2 housings
1.Thread the contacts of the twinkling bulb into the new housing and bend into the proper postition ( polarity doesn't seem to matter ).
do the same to the other bulb if you want
Step 3: Plugging it in
Plug in the light set
add flashing bulbs as nesesary
