Lookie What I Got! - Clear* Turn-Signal Bulbs

A couple days ago I took a look at my car and all of a sudden, the "fried-egg" front turn signals now bug the heck out of me!

This morning I decided today was the day I was going to do something about it. I checked NAM for insight. Lots of info, but not quite enough. I found a link to the perfect bulbs but didn't want to have to order anything. I didn't know if the "mod" was simple. The corresponding NAM thread provided some decent instructions- enough to motivate to go ahead do it. I went the to AutoZone website to see they had something in stock- but, no photo? (C'mon retailers- we want photos!)

I don't really like my local AutoZone so I went to Kragen instead. For once, Kragen didn't have what I was looking for, and AutoZone did (usually it's the other way around). So instead of ordering the $25 silver covered bulbs from, I got some "close-enoughs" for... $12! No shipping or waiting!
Popping them in was pretty simple. When the lights are on you can't tell the difference. When they're off- well, not exactly "clear", but much better than distracting orange "accents" . If I had known this was so simple I'd have done it months ago!

I wished there were better instructions on NAM so I wrote up my own:

The $12 bulbs I got from AutoZone: Sylvania "Silverstar" Part No. 1156A ST (edit: The actual part number is 7507AST, but those weren't in stock so I improvised)

Here's what it looks like in the box (there's only one bulb in this photo because I fitted the first one in the AutoZone parking lot).

Here's the back of the box.

Pop the hood bonnet and find the housing holder. This shot is the left signal, while leaning over the bumper looking into the hole. To remove- 1) turn it, 2) pull it! So simple for skinny-handed folks lke myself!

Here's the bulb in it's holder. Remove the OEM bulb. Also simple!

Replace it with the new bulb. Note: the pins on the side of the OEM are offset at 150-degrees. The pegs on the Sylvania are at 180. In other words, they don't match up precisely to the bulb holder- a little "dedication" and it fits right in. This shouldn't be an issue if you can secure the proper part.

Replace the bulb housing the same way you took it out- turn it til it locks into place.

Here's a before and after with the lights off:

Here's a before and after with the lights on:

*Not exactly "clear", there is almost no noticeable difference with the lights on. $12 and 10 minutes later, I'm a happy camper!

    That's a great idea - I'm gonna do the same. But my search came up with Sylvania 7507AST as the direct replacement (which should explain the 150 vs 180 offset)

  2. Thanks for bringing that up! That is the correct part number- They didn't have it at the parts store, and I was feeling adventurous!

    I'm going to do this too. Thanks so much for the instructions and the photos! :)
