The Side Repeater Lights on my DB9 have discolored to a Yellow’ish from the UV in the harsh California sunlight. I know, this concept is completely unfathomable to my readers in the UK, and probably a design issue the factory never considered – “Sunlight? Bahh – just make it waterproof you twit – this is England”. When I purchased my car from the DPO (Damn Previous Owner) it had the issue quite notably on just the left hand side assembly. I can presume he parked the car during the day with that side facing South.
The side repeater light is a turn indicator light mounted on the side of each front fender/wing. When new, the plastic assembly is a clear lens with some white. As you can see in this photo, the old one has got that ugly faded yellow plastic color compared to the bright, fresh and clean look of the new one.
I’ve wanted to freshen the look of this up so I ordered a pair of the assemblies and decided to replace them. Here’s how if you’d like to do the same for your car.
Note: If you just need to change a burned out light bulb in your side repeater, you can easily use this process below to see how to get to and change the bulb.
You just need one or two of the assemblies depending if you want to go to the trouble to change just one or both. I’d suggest doing both since it’s an easy process and they aren’t expensive. You can then be sure they ‘match’. The same part is used on either side.
They are Aston Martin part number 4G43-13K376-AA. You can find them online here for about $20.68 USD each, or for about $20.54 USD (£16.49) each by reaching out and contacting Rob Sims at HWM in England (where I got mine). As Aston parts go, these aren’t too expensive.
Note: The assembly DOES include a new bulb. If you are bulb shopping anyways, the bulb is a WY5W Amber that you can find online at Amazon.com for about $8 USD per pair. LED versions are also available since this is a standard format. [In a future article I will be covering replacement options for all bulbs in the car]
Interesting Footnote – A keen reader of the blog had noticed that the lamp looked identical to the one you would find on a Ford Transit van of the same era (more of that Ford Heritage – ick). They actually ordered one to find out, but alas the lens area was identical, but the body behind the lens wasn’t a match and didn’t snap properly into the fender. It was about the same price anyways, so not worth debating.
To just swap the assembly you really don’t need any tools other than your hands. I’d suggest having a clean, damp micro fiber towel to clean the painted recess in the fender while you have the assembly removed and access to the area.
As you’ll see in my procedure below you need to get access to the assembly you’ll need to tackle a few steps outlined in other articles, and those require some tools. Read on to find out.
The swap of the assembly itself will take less than 2 minutes once you have access. The process is simple, but you need to tackle a few steps first.
To get access to the assembly you will need to follow the steps covered in my other articles already:
Conceivably, if you have a full garage ‘ramp’ where you could raise the car, I suspect you could only remove some of the screws in the back half of the inner fender liner, and flex it out of the way to reach up to the assembly. But alas, my Sweetie still hasn’t let me get one and I make do using my floor jack.
Once you have access:
- Stick yourself inside the fender and look at the back of the Side Marker light assembly.
- Remove the electrical connection by squeezing in the wire band. I really, really suggest you check out my video below to see me show how to do this clearly. Super simple once you see how. Hard to figure out in a dark space.
- With the electrical connector now removed, grip the light assembly and turn it about 30 degrees counter clockwise (until it won’t turn any more) to release it.
- Gently ease it out through the fender opening and catch it with your other hand.
- Now is a great time to use your damp microfiber towel to cleanup the freshly exposed paint in the recess where the light assembly normally sits. You’ll probably have a mixture of dirt and wax residue that has accumulated in this hard to clean recess.
- Note that the opening in the fender is ‘keyed’ with a wider slot opening at one end. The lamp assembly will only fit in one way.
- Carefully insert your new lamp assembly into the opening, and rotate it back to lock it into position.
- Reconnect the electrical connection.
- The connector only goes on only one way. There is a alignment key on the lamp assembly that aligns to the connector. Check out the video to see.
- Tip – BEFORE you start to put your fender liner and wheel back on, now is the time to TEST that the light is actually working. Turn on the turn signal and make sure the lamp is blinking properly.
- Tip – Save the old bulb from the old assembly as a spare!
Finish up the process by checking out my other articles and videos on:
- Installing the front inner wheel liner
- Installing the road wheel
- Lower your baby off the jack
- And finally properly Torque the road wheel
Here is a quick video of the procedure:
Here are a bunch of high resolution photos of the light assembly for those so inclined to check it out up close.
