    Bulb type for front turn signal?

    Im pretty sure there 3157 but is there different types of 3157 bulbs i wanted to put silverstars in them and the socket is a round socket much different from the wedge style socket in the rear back up bulbs that i put 3157 silverstars in?

    A round socket bulb would probably be a 1157. 3157 is a dual diligent wedge base.

    Been ok. Thanks.

    1157 round base bulbs are mostly found in older vehicles. Are you sure you're calling it the right thing?

    Edit: Actually just found a video of a turn signal bulb change for '00-'05 Devilles. It's definitely a wedge type bulb

    Re: Bulb type for front turn signal?

    the rear reverse lights are 3157 wedge unless your referring to the side marker bulbs which are small 194 wedge aswell as the parking lights in the headlight the main turn signal in the headlight housing are round with a round socket i think ur right there 1157 want to order but need to confirm

    ----------

    U know what moist? i just thought of somthing on my old headlamps the bulb and socket where round but those headlamps where aftermarket junk i just bought new oem Gm headlamps to go with my restore job on her i saw the video aswell but the after market ones where not a 3157 wedge i got to check my new headlamps

    ----------

    and i just noticed somthing else that deville in the video those side markers looked like 3157's but my side markers take 194 small wedge and i can confirm that mmmmh this is weird

    according to the 2004 Deville Owners Manual - page 5-58 -
    BOTH the front turn signal - and cornering lamps are 3157 -

    the side markers are 194 small wedge
    correct -
    the side markers are the small amber colored light behind the amber reflector -
    on the side of the headlight -
    all they do is illuminate whenever the parking lights - or headlights are on -
    they do not blink/flash - or anything else -

    the cornering lights are the clear 3157 bulbs behind the big clear lens on the side -
    they illuminate with the turnsignal - but do not flash -
