Solution for LED Thin Line Side Marker Trailer Light

Question:

I have the Peterson thin line 427400 on a Winnebago Rialta, a couple bulbs are burned out and one of the lenses cracked so I thought about replacing them with new LED lights, do they not make this light in LED or which one is a good replacement

I do have a solution, but the Peterson Thin Line # 427400 doesn't have an LED equivalent. I could recommend a different light but that would require drilling new holes to get it mounted. What you can do instead is swap the bulbs to LED using the 194 LED Bulbs # ARC78FR. This will keep the same style and let you use your current holes for mounting. The one with broken lens will have to be completely replaced since there are no longer replacement lenses available.

I bought the lenses and bulbs from you The bulbs work fine, the lenses don’t stay securely, they are too big ??

@SizeD they should fit it is the same light with different branding. I'm not sure how old your old lights were, could be a slight difference in production or wear over time. I would throw some sealant around the edges of the lens to keep them secure since this is the only replacement available.
