Hi Dave,
I have a 20 Pack of #198 type LED bulbs for $17.59 at Amazon on order, will get them between 07.Sept. - 23.Sept. Will write about how they work out in an update on our travel blog. Yep, we live in Wheatley very close to you, which Jayco is yours?
Best regards,Benno Marlene and Benno's Odysseys on Land and Water
