Direct OEM-style incandescent replacement for the 1141 bulb — one of the most widely used bulbs in RV interior lighting. S8 shape, BA15s single contact bayonet base, 12.8V, 21 candlepower, 1.44A draw. Long life rating. 2 bulbs per pack. Clear.
The 1141 is one of the most common bulb types used in RV interior lighting — found in ceiling dome fixtures, reading lights, cabinet lights, and other interior applications across a wide range of RV brands and model years. When one burns out, having a direct replacement on hand means a quick swap rather than a trip to the hardware store or an extended stay in the dark.
The Valterra DG71206VP is a direct-replacement 1141 incandescent bulb from the Diamond Group by Valterra lighting line — the same bulb type, base, and voltage as the factory-installed original. The S8 shape and BA15s single contact bayonet base are the defining characteristics of the 1141 standard, and this bulb meets those specs exactly at 12.8V and 1.44A draw. Long life rating extends the time between replacements compared to standard service bulbs, and two bulbs are included per package so you have a spare immediately on hand. If your fixture currently runs the 1141 incandescent and you want a reliable like-for-like replacement, this is the straightforward answer.
Exact match for the 1141 bulb standard — same S8 shape, BA15s bayonet base, 12.8V spec, and 21 candlepower output
Long life construction extends the replacement interval compared to standard service 1141 bulbs — fewer swap-outs over the life of the RV
Two bulbs per package — replace the burned-out bulb and keep a spare on hand for the next time
BA15s bayonet base installs with a push-and-twist motion — no tools, no wiring, replaces in seconds
The 1141 is a widely used 12-volt automotive and RV bulb standard. Here's what the specs mean: S8 Shape: Single-ended globe shape, 1" (8/8") diameter — a compact, rounded bulb profile common in RV interior fixtures BA15s Base: Bayonet base, 15mm diameter, single contact (one pin on the side, one at the bottom). "BA15s" is also called a "1141 base" in RV contexts. Install by pushing in and twisting to lock. 12.8V / 1.44A: Designed for 12V DC RV electrical systems — do not use in 120V household fixtures 21 Candlepower (21CP): Light output rating — equivalent in brightness to other 1141 standard bulbs Common RV applications: Ceiling dome lights, reading/bunk lights, entry lights, exterior porch lights, and any RV fixture labeled "1141" in the owner's manual or fixture housing Cross-compatible bulbs: The 1156 is related but different — the 1156 is used for exterior turn/brake applications and is not a direct swap for 1141 interior fixtures despite sharing the same BA15s base.
The DG71206VP is a direct incandescent replacement — the same technology as your original bulb. If your goal is to reduce power consumption, extend bulb life significantly, or reduce heat output in enclosed fixtures, Valterra also offers LED alternatives that fit the same BA15s base: DG72602VP — Diamond Group 1141/1156 LED Replacement Flat Bulb, 165LM, 5500K, 0.08A, fully dimmable, 2-pack. 90% less power draw, 60% less heat, 5-year/50,000-hour guarantee. LED upgrades cost more upfront but last significantly longer and draw far less from the RV's battery — particularly beneficial for boondocking or dry camping where battery conservation matters. The incandescent DG71206VP is the right choice when you want a true like-for-like replacement at a lower cost, or when your fixture is dimmer-controlled and you've confirmed LED compatibility.
Replacing the 1141 Bulb: 1. Confirm the Fixture is Off: Turn off the light switch and, for safety, disconnect shore power or turn off the 12V battery disconnect if working in an enclosed fixture 2. Allow to Cool: Incandescent bulbs get hot — wait a minute for the old bulb to cool before removing 3. Remove Old Bulb: Push the bulb in slightly against the spring tension and turn counterclockwise approximately 1/4 turn — the bulb will release from the bayonet socket. Pull it out 4. Install New Bulb: Insert the new DG71206VP bulb into the socket, push in against spring tension, and turn clockwise approximately 1/4 turn until the bayonet pins lock into the socket slots 5. Test: Restore power and turn on the switch to confirm the bulb works Store the second bulb in your RV's spare parts kit — it's not if you'll need it, it's when.
