Pirate19Patio Bulb
Pictured is the "patio light" bulb I need to replace on my '92 Breakaway. The stamped number on the base of the bulb yields no search results. My concern with going to an auto parts place is I may end up with too "hot" of a bulb resulting in melting the lens cover.
Any suggestions, including the possibility of going LED, would be appreciated. Thanks all.

KevinI would go with LED (light emitting diode) replacement. Your bulb looks like an 1156 bulb. There are several LED replacements available. Some have more forward facing LEDs than others.

Mogan DavidI put one of these in the Bargman patio fixture of my Breakaway. I also bought both clear and amber new lenses for the Bargman.

RustyThe 5x5 25 LED bulb I got has apparently been discontinued, however:
http://dg-usa.com/#!/LED-Bulb-...047/category=1206569The 5x5 is VERY bright.
Google: 52532led for places that may still have them in stock. Expect to pay ~$30 each.

Pirate19LED it will be to replace the 1156-like bulb. Will go "forward facing". Had no idea they existed. Will post my decision and level of satisfaction. As always, all.

benebobBest part about LEDs is they don't attract bugs when on. Maybe they are smarter then we are? If you look on Ebay or Amazon you can find a 20 pack or so of 1156s and swap out all your old bulbs. Use something like a 1/10th of the wattage. One thing to be aware of is that LEDs only light on the right polarity so if you put one in and it doesn't light your wiring might be "backwards" try running jumpers to the opposite posts on the bulb before assuming it is a bad bulb.

carlflackJust turn the bulb over 180 degrees to change the bulb's polarity.......................Carl

Steve VWDepends on the bulb used:
The bulb shown has an 1156 style base, ie a single center electrode with socket as ground. They are normally wired with the spring center contact positive and the socket negative. The LED bulb expects that polarity. The old style Edison bulbs are a simple resistor wire and don't know polarity. It is possible that the socket is indeed reverse polarity and must be rewired.
Some bulbs are the 1157 style with two terminals on the base of the bulb. These can be used for two circuits when the socket is grounded, ie tail light and brake light. (BA15D socket)
An 1142 style bulb also has two contacts on the light base but is usually wired to a single filament using no socket ground. (BAY15D socket) The only difference in the bulbs is the bayonet lugs are staggered for the 1157 style but the lugs are even in the 1142 style and you can reverse the bulb.
These will indeed reverse polarity by simply rotating the bulb 180.
I had 1142 bulbs in several of the interior fixtures which are ungrounded. Most LED arrays are polarity sensitive, others by design are not. I had to rotate bulbs when installing to get them all working.

Not if you own a TVR. LOL I spent quite some time rewiring when I went to LEDs as they took the lazy approach when wiring. Spot on though with the polarity and how different bulbs can or can't be used. I would love to change out my tail/turns but haven't figured out how to make them work yet. Seems that the stop is the issue.

I had to wire an 1157 bulb in parallel to make both the tail and stoplights work.
