If I recall correctly, the 1056 is an older bulb of a higher wattage,
but with roughly the same light output as the 1156. The 1156 is 25
watts, 3.2 c.p. Not too efficient ... then came the slightly better
1073.

JC Whitney has much better halogens to replace those old bulbs.

Yes and no. They will both physically fit and work in the same socket,
but their wattage is different. One will be much brighter than the
other. I forget which is which, but one is usually used for back up
lamps and the other for tail lights or turn signals.

I'm not familiar with the 1057.  But the difference between a 1157, and an
1156 is a big one.  An 1157 is a dual filament bulb (two contacts on the
bottom) used for tail lamps with integrated brake/turn sig.  An 1156 is a
single filament bulb (only one contact), could be used for dedicated turn
signals, marker lamp, or backup.  If a 1057 and 1157 are the same then the
1057 and 1156 are not interchangeable.

Mike--

Under which brand are you finding 1057 bulbs? This is not a standard
number.

1141 and 1156 are interchangeable, though 1156 is brighter.  There are
numerous different bulbs on the Ba15s base used by these two bulbs--do you
have a special application?

Mike,
No, they are very different.
The 57 bulb has two filaments and an offset keeper on one side so that
you put it
into the socket in the proper orientation.
The 56 bulb will go in either way and has a single filament.
Always replace a bulb with the same bulb.  Always replace an amber bulb
with an
amber bulb etc.

Guys ... you GOTTA read the posts.

He said 1057, not 1157. The 1057 is all but obsolete. it was used as a
tail/marker lamp. The 1157 is a dual-filament/tri-wattage bulb, still
popular in tail-stop-turn signal applications, where the one bulb does
all three jobs.

Bottom line: and 1156 will replace a 1057.
A 1073 will be a better replacement; lower wattage, same brightness.

The halogen replacements are better still, with over three times the
candle-power per watt.

Just make sure tou keep things relative when changing bulbs; that is:

The stop lights are brighter than the tail lights. The back-up lights
are very bright, and the turn signals, if combined with the
taillights,can be clearly seen over them as well.

These are the areas where most mistakes are made with bulb
substitutions.
