Paging Daniel Stern - amber turn signals
Just curious about something.
I've been trying to find a set of replacment amber 7440 bulbs for the front and rear turn signals on my 2004 Subaru Impreza WRX. I don't need them right now, but I keep several spare bulbs in a kit in my trunk. Can't seem to find the amber ones in the aftermarket. Thought about the dealer, but that'll be a last resort. I've tried the usual sources (AutoZone, WalMart, Kragen) and have only seen the clear 7440 from Sylvania (made in Japan). Is this bulb supposed to be that hard to find? Also curious about your opinion of those chrome colored turn-signal bulbs that glow amber/red/etc. I don't particularly want them, but is there anything inherently wrong about them? |

I actually like the Diadem type bulb better than the plain amber bulbs. The coating can never fade or burn off as it does with ordinary polymeric amber coatings (amber-glass bulbs are almost extinct due to their Cadmium content). Also, there may be a visual benefit to this type of bulb in bright-sun conditions, but it hasn't been looked at formally yet. The Diadem bulbs are made in red, too, but not for drop-in replacement of any other bulb type. They're permanently soldered into the bulb holder on e.g. the MINI Cooper factory clear-taillamp package that was briefly available a few years ago. Burn out a brake light bulb, go spend a few hundred bucks on a new bulbholder assembly! -DS |

Or are they now passe? Also are the amber ones available in a non-index base dual filament bulb e.g. 1176?

Is there any legitimate method for turning a clear glass bulb into an amber one? I'm not nuts about the lack of contrast between the turn signals and headlights, but I'm also not prepared to modify the very rare and expensive parking light housings with a different socket... nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |

There are a few different clean ways of doing this. The cheapest and easiest? File off one of the index pins from a BAY15d-base bulb! If the socket's not completely shot, the one pin should hold it in place OK. If not, you can shim the bulb with a wrapped strip of HD aluminum foil. If that's a no-go, or if you want to be able to use a higher-output bulb than an 1157, e-mail me a picture of the assembly you're working with (pref. disassembled) and I'll send you some solutions. |

I'm not trying it myself, but I've heard of people taking clear bulbs and marking them with a clear orange sharpie. I wouldn't think it's unsafe, but it probably wouldn't look that good. Don't know what the heat would do - it just might start flaking off in the assembly or become discolored. |

I can try that... once I get the passenger side back from the chrome shop. The metal shell of the socket is crimped to this big chromed potmetal assembly; I don't see any modifications being practical or honestly possible without a high potential for damaging something expensive. Right now I have something kludged together on the pass. side as a placeholder that I'm not real happy with, but it lets me drive the car until I get the good one back. Worst case, the correct white bulbs are available in a 12V version (car has been converted) nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |
