The Harley Davidson Fat Boy

Today we're taking a closer look at adding lights to our latest purchase - the gorgeous LEGO Creator Expert set 10269 - Harley Davidson Fat Boy.

We were so excited to pick up this model we did a quick project on adding lights and this went straight to Instagram.  Now we've gone back to it, improved the lights, and have photographed the process so you light up yours too!

The Model

Here's the lovely motorcycle.  Shame about the lack of chrome but it would need a LOT of chrome to do it justice.  It does look great and the details and proportions are perfect.

Lighting Options

This one should be pretty easy - we need head lights and tail lights.  The only other option on such a set would be indicators.  There's two on the handle bars and two at the rear of course.  

We decided not to touch the indicators.  Having two of them blinking constantly doesn't sound appealing really.

Installing Lights

Let's start at the back - carefully remove the module with the number plate and trans-red light pieces.  If any of the jumpers come off with it just replace them on the bike.

Then lift off the passenger seat pad, and carefully remove the main seat and the curved centre console section of the fuel tank.  These may come off together or separately - either way works just keep them safely to one side.

And now carefully remove the side of the fuel tank.  This tends to leave behind the pieces with the technic pins on them, or just fall apart.  No problem just reassemble the side panel and keep it safe for now.

Okay on to the good part.  Take the trans-red pieces off the number plate.  Put the two curved end pieces back in your Lego stash - we won't be using them as you can't easily fit these lights underneath 1x1 tiles.

Take the first Red 30cm bit light and feed it through from underneath.  Place is between the two centre studs and refit the 2x1 trans red tile.  

Then repeat this for the two end studs - add a 30cm Red Bit Light, carefully squeeze a 1x1 trans red plate on top, and fit the cables through the gap above the number plate.

Once done twist the cables together into a neat bundle.

Now that's done it's time to fit the number plate back.  

Attach a 6 port expansion board to the plugs on the three lights and feed the board up underneath the back of the bike as shown.

Leave the cable loose and refit that number plate.

The 6 port expansion board will fit nicely just above the engine - wrap that excess cable around the board several times so there's a little slack as shown below:

Let's move on to the front.  Carefully pull that headlight block forward and it'll come off in one neat piece.

Remove the 4x4 round pieces and gently separate that black robot arm to separate the housing as shown.

Take your four 15cm White Bit Lights and fit them one by one, with a trans-clear stud on top of each.  

Feed the plug down through the middle of the 4x4 plate, hold the bit light loosely on top of a stud, and lower the trans-clear stud on top of it.  

Repeat this for all 4 white bit lights.

When that's done fill in the rest of the 4x4 plate with more trans-clear studs.  This gives us something to fit the front headlight cover to, and spreads the light around nicely too.

Whilst you're there, go ahead and neatly braid those wires together too.  This makes the wiring easier and neater.

Now feed that neat bundle of wires back through the headlight housing, re-attach the headlight to the housing and close it all up again.

Mounting the headlight again is pretty easy - just feed the wires through the middle of the forks frame as shown so they're not too visible, and push the headlight housing gently into place again.

Time to wrap this up!  Connect up those two expansion boards with a little 5cm connecting cable so we have a full circuit.  

Now we just need power and to put it back together.

Whatever power source you want to use, feed the cable up from underneath the bike and hide it behind the exhausts.  Gently feed it over the engine block and connect it up to either of the 6 port expansion boards.

You may find needle nose tweezers makes it easier to guide the cable through.

For our demo we used a 50cm connecting cable here, and then used an AA battery pack for power.  You could just use one of our tiny Flat Battery Packs which is a good fit for the 4x6 plate at the very base of the Harley.  You could use a few sticky pads to hold it in place so you can easily turn it on and off.  Just remember to position is so you can easily change the batteries still!

Or of course you can use a USB adaptor or similar for a more fixed option.

With power connected, make sure the two expansion boards are tucked in above the engine then carefully push the side of the fuel tank back on.  When secure you can re-fit the centre console, main seat, and then the passenger seat pad.

And we're done!  All back together with almost no visible wiring for the lights.

Parts Used

We used the following components for this project:

To power the lights we added:

But instead of those parts you could easily connect a flat battery pack and stick this underneath the engine block, or connect a USB adaptor cable instead.

The Finished Product

And there you have it - simple but effective.  What do you think?

If you'd like to buy the parts used in this kit then we've provided handy links above.  You can also contact us for a custom bundle with just the parts needed (rather than full packs of everything) and we can help with the Lego parts used too.

Until next time - Happy Building!
