I'm working on the light bars that sit next to the aircleaners at the moment. I want to get anything attached to the body done before i paint in case i have to make holes, cut bits out etc.
This:


But am in a dilemma. I got a load of bezels from RCT which are just awesome little pieces of work, and i'm using them elsewhere so i'd like to use them here. But, because the bezels end up being 6mm across for a 3mm LED, they take up heaps more space when theres 8 in a row. Factoring 1mm gap between each, they come in at 57mm, which makes it taller than the air cleaner. But as you can see in the pic, the group should be smaller. At that length it also puts the lowest 2 below the top of the fender.

If however i use the 3mm LED by itself, i can make it much smaller at 33mm which puts the appearance much closer to the real thing. But then i dont get the look of the bezels. Plus the blue LED's actually have a clear body so wont look right when not lit.

This is a size comparison, i mocked up the full 57mm version in styrene to check.



The bezels look so much better, but take up a lot more space.

And to make matters more complicated, compared to the movie truck, the air cleaners i have are actually shorter, they should go down to the bottom edge of the cab, which would make the bar with bezels work better.

Thoughts?

You know when i ordered the truck, i thought "this will keep me occupied for a couple of weeks...".

4 months later, and still going!

But i'm happy taking my time, spending as long as i need to on each part to get it how i want it. Probably a couple more months to go before i consider it finished i think. Certainly be taking my time with paint. Light coats, days between colours to let it cure. I'm not an absolute perfectionist, but i like to try my best.

You're doing an amazing job. Would it kill your sense of perfection to use the bezels, but only go with 6 lights, rather than 8? From this pic, it looks like things would line up about right:



That's the way I'd go, but I would have given up a while ago

How about this:


Thats with a 3mm orange LED for testing. I think once the LEDs are installed, i can put a touch of transparent blue paint on the lens should do the trick.

But, i need to test one first. Photography is another hobby of mine, so i know that putting a clear blue over blue light will act like a filter to the light from under it. If the blue from the LED is a different wavelength than the blue paint, i'll get bugger all light coming through. May have to use a cool white LED with clear lens, and transparent blue paint.

Do i think too much about these things? lol

Not quite as neat as i'd like, but good enough from a distance.
Now to make a second one.

Bumper with bezels installed, and hidden screws.



Then made up the LED loom for it.

Looks fantastic. Glossing my cab tonight and then off to the LEDs as well. How are you planning to run all the cables around? I was concerned about all the wires with just the MFC. Looking at yours, I should have no issues!

Ill be trying to make the looms as compact as possible. The bumper leds will be fed up in front of the servos, then i can run the loom in the frame beside the gearbox. Possibly.

I'll wire them to the bit of prototype board, then connect that to a distribution board where the rest of the lit parts will also connect.

If i've counted right, there will be another 77 leds besides the 15 i've done for the bumper.

Why not wires them in series so there was only one wire coming off the bumper?

If they were all in series, they wouldnt all get lit. Wired them up in parallel.

You just need the right resistors. :-) I wired mine up that way. Worked good.
