I have a 1004 bulb which has blown - the interior light. What wattage bulb/type will replace the 1004? Thanks |

Why do you want to change the size? 1004 specs. Amperage: 0.94 amps Base Type: BA15d Bulb Configuration: B6 Bulb Part Number: 1004 LL Bulb Type: Incandescent Color Temperature: 2800 K Color: Clear Diameter: 0.75 in DOT / SAE Approved: Yes Filament Configuration: C-6 Filament Quantity: 1 Length: 1.75 in Light Center Length: 1.06 in Lumens: 188 lm Package Quantity: 2 Rated Life: 325 hr Voltage: 12.8 v Wattage: 12w |

Replace your burned-out 1004 with...a new 1004.

Where do I get one? In Australia 1004 means nothing to the auto shop guys, hence my Q on the wattage. Is eBay item number:111669236504 ok for the internal courtesy light? |

Yes, those GEs are correct, but you can get the correct bulb locally. Narva Australia #47004, second item on this page: http://www.narva.com.au/products/browse/interiorpark |

Sweet! How can you test them with a multimeter? |

Quote: Check filament's resistance (Ohms) with VOM. Keep in mind Watts is a rate, or Watts = ohms x voltage.
Warning the above formula is junk science for this example spewed from an addled brain. Disregard this post and skip down a few posts where I correct what was said here.... just below where Dan tossed down a flag on the play.

That works for resistors, but not for light bulbs. You can check whether the filament is intact (if so, you get continuity between the two base contacts of a 1004 bulb), but that's it. |

Sorry for steering in wrong direction, brain fart attack. Dan: Quote: That works for resistors, but not for light bulbs.
OK Hook up the bulb to 12v, illuminate it, and measure amperage drawn. Watts more or less is the same "number" not units as Volt Amps. Suffice it to say close enough for this illustration where watts or volt amps = amps x voltage. As filament heats up it its resistance increases. So as Dan implied, cold filament = no resistance or close to zero ohms measured; there is some negligible resistance in any conductor. When an incandescent light bulb is turned on there is an instantaneous surge of current through room temperature incandescent filament which quickly, no, almost instantaneously throttles current flow as filament heats up becoming more resistant. This takes place in micro second. |
