replacing bulbs in lair playset?

I just bought a thundercats lair. battery terminals are clean on the playset and mutant gun.

i know theres supposed to be light bulbs inside both and both are equipped with what appears to be light sensors.

you play in a dim lighted room and shoot at eachother and the light from the bulbs is supposed to shine into eachothers light sensors to decrease the others shields.

when you push the buttons there is laser sounds but i don’t see light coming out of either toy.

so obviously i might need to replace the bulbs but i can’t seem to take it enough apart to gain access to the bulbs.

anyone have this problem? and have successfully replaced the bulbs?

the plastic is ok but might be fragile so i dont wana break anything.

It has been years since I took a lair head apart, so use this as a general guide…

3 screws hold the two halfs of the head together, gently remove them and wiggle the halfs just a little until they slide out of the base.

There should be 2 screws holding the black bulb assmbly together, remove them

There should be 2 screws holding the part with a sticker on, remove them.

That should give you access to the bulb. Go to your local Radio Shack and get the replacement bulbs. I believe they are the same as for the laser saber backpacks.

Hope my memory is right, and that this helps.

very helpful i figured it out thanks!

lair works perfectly
