1 - There are now two light housings on either side of the rear.
2 - Each housing has two single-filament bulbs in them.
3 - See above
4 - Flash-All 999 (4 wire)
5 - 6v
One thing that I read is that I should have gotten myself a powered converter. If I wire in an additional set of incandescent lights AHEAD of the converter, I start to see some action. This may be a step in the right direction, however if I can get around using the converter at all, them I'm up for that!
OK, but here is what you said just now.
Two housings on each side= 4 total housings
Each housing has Two bulbs= 8 total bulbs
Please try to be careful. I can't go forward with this kind of communication.
I guess we can make the 4 wire flash all 999 work, but it's really adding to a goofy way to go.
It's probably too late to return to normal, but would you consider one light housing on each side with one dual filament bulb in each and a 7 wire Signal Stat 900 switch?
It's also time to go 12V, you are improving your truck lighting and etc. This needs 12V for a lot of reasons. Easy to do. You are buying too many band aid gizmos to compensate for things. Let's slow down and back up a few steps.
Don't get discouraged or take offence, we are here to help.
