Flickering LED Lights

Accept the [Flickering LED Lights] quest?

So now Hui Koon Kit is starting a LED Light collection. Madness!

You can get them by hunting Stoplight Ghost monsters at the Three-way Intersection. I'm starting to have doubts about Hui Koon Kit's sanity, but a quest is a quest! Good luck.

You're not quite ready for a quest like this...

Hey, you're back!

I'll give you your reward, then. Nice work.
